1994 Halloween, the United States Midwest Kenting University city, a tense speed skating competition is being staged, just at this time suddenly killed a player wearing a pumpkin head, "pumpkin head" after the first, the first to cross the finish line, the mask removed, all the Kenting Campus girls are forgetting to shout up! --"Luhang, Luhang ......". Luhang revealed his childish mischievous smile, quickly disappeared in the crowd, he was preparing to participate in the weekly meeting of the physics group, as "Li Zhengdao Physics Scholarship", Luhang is the core of the group, his mentor, the American astrophysicist, Prof. Gordon, also regarded him as a favorite disciple, in the view of Luhang! Gordon was both a strict teacher and a father, and his serious and paranoid character would not allow anyone to be late.
Lu Hang was rushing through the gate when he received a cell phone call from his girlfriend, Yaping, asking him to go to her dormitory to pick up a dance accompaniment tape. Luhang can only turn back to drive to the student residence, the road because of the slippery road also because of the anxiety, Luhang brakes and the car in front of the rear-end, apologized Luhang was the other car rock band chatter insulting the Chinese behavior of anger, up to a punch. At this moment, a small-town policewoman, Katie, arrives in a police car and helps Luhang out. The two became acquainted.
Luhang rushes to Yaping's side, who is now dressed in a dance costume and putting the finishing touches on her performance in the university's small art department theater. Yaping complains to Ruhang about the triviality of the preparations and the intense pressure of the performance, but Ruhang reassures her with the words, "You're the best". Meanwhile, in the small conference room of the Physics Department, the famous astrophysicist, Gordon, is late for the discussion on the subject of Luhang, who hates students who are not punctual, and although he is able to forgive the late arrival of his favorite student Luhang, he is still a bit upset. Luhang finally arrived, the meeting began, but this time the regular meeting Luhang asked to break the routine, first of all, he spoke to introduce the progress of his own project, because he had to rush time, otherwise he would miss Yaping's graduation performance. Gordon's irritation almost comes to a head, but he holds his tongue and gets up to leave without a word after Ruhang leaves. Luhang's good friend Hai Guang commented on Luhang with envy and emotion, while Lin Yan Ping, the president of the association of Chinese students at Kenting University, smiled and reassured Hai Guang that he would have that day too. After that, the number two person in the subject group, the playboy-like associate professor Smail, faced with the stalemate, could only announce that the subject research meeting would be rescheduled to reconvene at nine o'clock tomorrow.
Yaping's graduation performance finally began, Luhang hurriedly rushed to the theater, Yaping's Chinese folk dance "Fan Dance" displayed the oriental flavor fascinated the audience in the seat, but a group of rock musicians on Luhang's side of the discordant sound, they raised a loud cajoling, and even made some nasty gestures to insult Yaping on the stage performance. Luhang can not tolerate others on the Yaping slight, indignant protest, the rockers found Luhang is the morning and they chased after the young man, and so more energetic, Luhang can not stand it, bravely swung their fists, the venue quickly turned into a riot, Yaping's performance was forced to interrupt, a self-centered white fat police officers with Katie arrived to stop the riot, and take away the leader of the troublemakers Luhang! .
At the police station, Luhang is taunted by the police, and he angrily fights back, but the white police officer mistakenly thinks that he is going to attack the police, and pulls out his gun and puts it to his head, and the angry Luhang quickly calms down, and for the first time, he feels the beauty and power of the gun. In the detention room, Ruhang completes the data Gordon asked him to prove, but because of the police's deliberate difficulties, he was locked up for 24 hours, he hurriedly rushed to the school, and when he was organizing his poor grooming, he was again seen by Gordon, who mistakenly thought that he was indifferent to the tardiness, and smashed the cup into the mirror that Ruhang was facing, and the shards of the mirror cut Ruhang's face, and Ruhang was greatly insulted, and he was injured to attend the meeting, and after producing the data he asked for, he fainted. He fainted in the subject room after presenting the requested data.
Yaping, who had been worried about Luhang all night, finally found Luhang, and the two met and argued about yesterday's graduation performance. Yaping complained that Luhang never learned how to make concessions, but Luhang felt that there were some principles that had to be adhered to, and there was no way to make concessions. Yaping is qualified to audition for the Broadway show. Luhang is excited and offers to accompany her, but Yaping feels that Luhang's project is too stressful and urges him to stay in Kenting. Luhang will arrive at the subject group and spend the overnight time to complete the task set by Gordon, unexpectedly appearing in front of Yaping who is preparing to go to New York, Yaping is touched by Luhang.
Yaping's audition on Broadway was a great success. Ruhang and Yaping happily strolled through the streets of New York, but accidentally found Gordon's secretary Jaeni and Professor Smail, Jaeni threw a note to Ruhang asking for help. Following Jenny's directions to the room, Ruhang rushes in and discovers the scandalous behavior of Smale, a sexual deviant.
After returning to Kenting, Yaping began to wait for his review notice for Broadway, while Ruhang hid in his private lab fiddling with a new subject of his own interest. Ruhang's private lab is accidentally discovered by Gordon, who demands that Smale shut down the small lab immediately. Smale finds Ruhang and prepares to tell him about Gordon's decision, but is intrigued by Ruhang's presentation of his new subject, which the academic speculator sees as promising, and promises to help Ruhang get published in a journal, which he agrees to do for the sake of the subject, in collaboration with Smale. At the same time, Gordon accesses the information on Shi Keng-yu, another recipient of the Li Cheng-dao Physics Scholarship recommended by Luhang.
Shikongyu receives a job offer from Prof. Gordon. Luhang is excited to tell Haikuang, but Haikuang warns him to be careful, as he trusts his friend and his own strength.
Shek Keng-yu came to Kenting University and accidentally bumped into Yaping, and was quickly attracted by Yaping's nobility and beauty. Luhang holds a small academic salon for Shi Keng Yu in order to get him into the role quickly, and introduces him to well-known professors in Kenting University. At the latest regular meeting of the Physics Department, the seating order was changed, Gordon's left hand side was seated with Shi Keng Yu, the two Chinese students were seated facing each other, Luhang's face was slightly surprised, but not surprised. Once again there was a small hiccup at the subject meeting when Katie, the policewoman, delivered Luhang's lost bamboo flute, complete with a beautiful leather case. Luhang likes it very much, and feels at ease with the cheerful and straightforward Katie, who in fact has a crush on the Chinese boy that goes beyond friendship. Gordon is extremely offended by this little episode and hands Luhang a note in Chinese pinyin that says, "Playing with things destroys your mind," which makes Luhang laugh.
To welcome Shi Keng-yu, who is new to Kenting, Luhang treats her at a Sichuan restaurant. At the banquet, Shi Keng-yu discovers that Yaping is Luhang's girlfriend, and she is a bit disappointed. Through careful analysis, she realizes that there is an irreconcilable conflict of personalities between the two intimate lovers. Elegant and gentle little attentive behavior, quite a Yaping happy to be used. This, however, made Luhang feel bad in his heart, and he had no place to vent his feelings, so he had to fight with other foreign students on the wine.
A new batch of international students is coming to Kenting, and the Federation has arranged for Luhang to take care of the three Chinese students, Li, Ji and Ouyang. The roommate, Grant, who lives with Luhang, is an eccentric American who usually forbids Luhang to bring anyone, especially women, to his home. In order to solve the problem of accommodating the Chinese students, Luhang tries his best to finally impress Grant with a game, so that the three international students can live in the house without any problems. However, in the end, because the living habits of Lao Li and the others are not compatible with the Americans, which ultimately led to the disagreement, Lao Li took the three to move to Shi Keng Yu's place, Xiao Ouyang understands Luhang's dilemma and insisted on staying, Luhang thanked her for her support, but finally let Lao Li take her away.
Lu Hang is working overtime in the office to help Gordon make up for the work he did in the reception of the foreign students, while Hai Guang tells Lu Hang that he saw Shi Keng Yu hugging Yaping in front of the supermarket, Lu Hang doesn't believe it, but he's so upset that he finally finds Yaping, who complains about Lu Hang's lack of concern for his own dance career. In the heat of the moment, Luhang blurts out that Shi Kengyu is hugging Yaping, and Yaping thinks that Luhang is spying on him, and is disgusted and can't accept it. Luhang, who is depressed, runs to the garden to play the flute, but accidentally helps Katie, a policewoman, to subdue a robber. Katie gives Luhang three passionate kisses as a token of her appreciation, which makes Luhang rather embarrassed. The annual graduation defense of doctoral students is about to start, and Lin Yanping is the first doctoral student to defend. Luhang is planning all kinds of details for Lin, and Lin listens to him, but when it comes to the issue of clothing, Lin insists on wearing a Chinese dress, and Luhang readily agrees to it when he realizes Lin's intention. Just as the two men were making their speeches, the phone rang, and Lin's wife was having a premature hemorrhage. Lin Yanping ran to the hospital without a second thought, and he couldn't care less about anything else for the sake of his wife's life. Luhang walks into the conference room and explains everything to Gordon, and all he gets is Gordon's ranting and "He'll never get a degree from me in his life". After some effort, Gordon agrees to give Brother Lin another chance within a year, and Ruhang leaves the conference room only to learn that Gordon's wife died last night.
Luhang is trying his best to help Gordon with a set of conjectured data, but after using various methods, he realizes that it's a set of data that can't be proved at all, and he points out the problem directly to Gordon, who believes that Luhang didn't try his best. Luhang is happy to relax, he believes that this is a set of data that no one can prove. At this moment, Katie comes with a sunny face and invites Luhang to go shooting with her, and Luhang can't refuse this proposal due to her special fascination with guns. Luhang's first shooting result was surprisingly good with 9 rings, which surprised Katie. The game is so enjoyable that the two of them go to a cafe to continue their conversation, where Luhang finds Yaping returning to Kenting from the re-test. Because of Luhang's impolite intervention, the conversation between Yaping and the Broadway agent ends unhappily, and Yaping complains that Luhang's behavior is once again ruining his future. Yaping goes to Brother Lin's house to complain about Luhang's unreasonable behavior and meets Shi Keng Yu on the way. After Yaping arrives at Brother Lin's house, Shi Keng Yu comes to the house uninvited, and once again wins Yaping's favor by his excellent cooking skills and considerate care. When Yaping sent Yaping home, Yaping invited Shikongyu to his home, but he accidentally bumped into Lu Hang, who came to celebrate the third anniversary of Yaping's acquaintance. Shikongyu wisely left, and Yaping and Lu Hang embraced each other, and Yaping asked Lu Hang to hold her tightly, as she was afraid that she would not be able to control her own heart, but Lu Hang was puzzled by everything.
Small Ouyang moved into a new home, life is inconvenient, begged to Luhang, Luhang immediately drove her to the Sunday thrift market to collect furniture supplies. At the yard sale, the childlike Ouyang is curious about everything, and the two of them have a great time shopping. What's more surprising is that they met Lao Li here, who gave up his studies to run a Chinese handicrafts store in the market, and Lao Li, who is quite a businessman, is doing a good job.
At the regular meeting of the project team, Shi Keng-yu announced that he had proven the data, and Gordon praised Shi Keng-yu, while criticizing Luhang for not paying more attention to the project. After the meeting, Lu Hang was on the computer to prove the data again, but the result was still unavailable, he found Shi Keng-yu, the other party had to admit that he used a small means to deceive Gordon, Lu Hang was very surprised, said that the scientific data of the lack of rigor will make Gordon make a big joke, Shi Keng-yu said his own theory of expediency, Lu Hang can not accept, but can not tear down his old classmates, the data problem will not be resolved.
On New Year's Day, Ringo organizes a two-day trip for Chinese students to a nearby carnival, and then holds a poetry reading that has been in the works for a long time, but Luhang is depressed and doesn't want to go. When he meets Yaping, he realizes that Yaping is tense about Broadway and changes his mind about taking Yaping to the event.
On the tour bus, Lu Hang was ready to distribute the mineral water he bought to everyone. Shi Keng Yu, however, moved a large box of drinks and blamed Lu Hang for buying discounted water for everyone to drink and enthusiastically distribute to everyone. Luhang gets very angry and gives all the water to the driver. Yaping and the car full of people feel embarrassed, and Yaping complains that Luhang has not learned the grace that Chinese people have to deal with this kind of thing at all. At the amusement park, Luhang is obsessed with the shooting game and forgets about his promise to ride the roller coaster with Yaping. Shi Keng Yu takes the opportunity to act as an escort and watches the two of them laughing happily on the roller coaster. On the grass he happened to remember a research on the solution to the problem, work forgetful he immediately took the bus back to school, but forgot to say hello to Yaping.
At the Mardi Gras party, Shi Keng-yu sang a wonderful Tujia song, and Yaping was so moved by the song that he couldn't help but come up to dance with her, and then the two of them f***ed around for a while. The office is seeking proof of the problem Lu Hang was attracted by a fire, it turned out to be Katie to invite Lu Hang to participate in the carnival square activities. Luhang can't let go of Yaping in his heart and returns to the carnival with Katie, and runs into Yaping and Shi Keng Yu dancing obliviously, making Luhang even more depressed. When the carnival bell rings, people in the square kiss each other enthusiastically, and under the influence of the joyful mood, Luhang takes Katie by his side as Yaping and kisses her obliviously. Ruhang went back to the office to work hard. Luhang in the office nibbling flapjacks act calculation, Gordon came over to probe the head, Luhang did not notice, Gordon reversed to get him a bottle of water to bring, reminding Luhang don't choke on their own, master and disciple heroes and heroes.
The student council bus arrived back at the school in the afternoon, people dispersed to say goodbye, Luhang drove to pick up Yaping, all of which was watched by Shi Keng Yu.
At the regular meeting of the project, Luhang put forward his own views, as well as the current trend of the project team for the casual use of data without validation to put forward their views, but unexpectedly Gordon did not listen to the opposite views, Gordon even threatened to terminate the labor contract with Luhang. Luhang is depressed and wants to talk to Yaping, but Yaping doesn't answer the phone when he hears it ringing. When Yaping calls back, Luhang has turned off his phone. Yaping calls Shi Keng Yu to ask if it was him who called, and Shi Keng Yu admits it and invites Yaping to go to the supermarket for shopping. When Shi Keng Yu drives to pick up Yaping and finds Luhang staring at him, he deliberately stops the car and tells Luhang that it was Yaping who asked him to go to the supermarket. Luhang warns Shi Keng Yu not to hit on Yaping, but Shi Keng Yu asks Luhang to respect Yaping's choice. When the two of them pull up to Yaping's house, Luhang asks Yaping to get into his car, but Yaping rejects Luhang on the grounds that he has an appointment first, making Luhang extremely depressed. When he waits for Yaping downstairs to talk to her, he finds Shi Keng Yu kissing Yaping goodbye. Unable to control his emotions, Ruhang punches Shi Keng Yu, and the two of them fight together; Yaping tries to pull the two apart, but Ruhang accidentally hits him on the bridge of the nose, and the fight stops. Ruhang tore his shirt to stop Yaping's bleeding, but Yaping refused Ruhang's touch.
On Saturday, Luhang's sister, Ruyu, arrives out of the blue, and it's Gretel who opens the door. The three of them spend a pleasant time together after Luhang's return, as Luhang's concern for her makes him surprisingly unresistant to the Chinese woman. Ruyu offers to let Luhang take her to meet Yaping. Luhang drives to the dance department with her sister in a hurry, only to find Yaping intimately with Shi Keng-yu. Luhang has to lie and tell her sister that Yaping has a performance to go out of town. Sister notices something unusual about Lu Hang and finds Yaping alone and pleads with Yaping to be more sympathetic to Lu Hang's impulsiveness. Meanwhile, Ruyu also finds out that Luhang has a revolver and is so worried that she throws the gun into the river while he is away.
All the computers in the Physics Department were attacked by a virus, and Professor Smail's office was burglarized, all the information of the paper on the new topic of Chaosology that Luhang had given to Smail for publication were gone, Luhang was very annoyed. On the other hand, Yaping also receives bad news that Broadway has accepted a younger dancer than her. Luhang tells Yaping that she should keep fighting for it, and Yaping expresses her difficulty in accepting Luhang's thoughts. Shek Keng Yoo, on the other hand, is nice enough to say that girls are supposed to be pampered by men, and it doesn't matter if they fail. Yaping should enjoy her own happiness, and Yaping's bad mood is instantly soothed by Shek Keng Yoo. The Chinese sympathy troupe came to the United States to perform, performing the dance of the very girl who took Yaping's place, and the dance was also choreographed by Yaping that year. Luhang impulsively states that the troupe should not perform this dance, while Shi Kengyu is good-natured enough to discuss with the troupe to let Yaping perform once. Yaping is simply unable to resist the temptation of the stage and once again falls on Shi Keng Yu's side.
After the New Year, everyone's work started normally again, but Lin collapsed in his office due to overwork. Lu Hang nervously opened the door for Brother Lin to go to the hospital for checkup, and it turned out that Brother Lin was in the advanced stage of liver cancer. In order to let Brother Lin get the best treatment, Lu Hang approached the vice principal, Mandelin, and hoped that the school could provide the relevant treatment. Mandelin agreed to Lu Hang's request, and at the same time, she proposed that she hoped that Lu Hang would be able to leave her own daughter, Katie, and Lu Hang was perplexed. Luhang takes good care of Brother Lin, who calmly talks about this and that. He thinks that Luhang, who seems to be strong but is actually simple and unsuspecting of people, will suffer a great loss in the future if he doesn't accept the lesson.
That night, Luhang was at home checking the internet, and suddenly realized that his new thesis had been split and appeared in all the major journals, and all the autographs were signed by Smail. Luhang called Smail's office, and Smail categorically denied that the article was from Luhang's hand. Luhang finally realized the truth of the office theft and virus attack, and in an abnormal agitation, he took a gun and rushed to Smail's office, threatening to kill him, but was pulled down by Hai Guang.
The next day, Luhang was detained on suspicion of murder with a gun. The police asked Hai Guang to be present to testify, Hai Guang refused. Smail found Shi Keng-yu and asked him to work with Hai Guang. Shi Keng-yu readily agreed. After Shi Keng-yu's lobbying, Hai Guang was still hesitant, but at this time, Xiao Ouyang, whom Hai Guang liked, was running around for Lu Hang, and his jealousy made Hai Guang firm in his determination to testify against Lu Hang.
Brother Lin died in the hospital, Lu Hang in prison got a strong premonition, he went crazy and asked to go out to see Brother Lin for the last time, he begged the sheriff, begged Katie, begged all the people. Katie finds her mom, Mandelin, in order to free Ruhang, and Mandelin offers to leave Ruhang on the condition that Katie refuses. In the end, Gordon stepped in and vouched for Luhang, who made a mad dash to the hospital, found the bed empty and hugged Brother Lin's baby, Doudou, and let out a cry.
Katie finally agreed to her mother's terms, Luhang was released. At Brother Lin's memorial service, Shi Keng-yu called for donations to help sister-in-law Lin's mother and child, and Luhang said that sister-in-law Lin would not want it, and everyone thought Luhang was cold-blooded. Luhang ignored the crowd's comments and ran alone to play the flute at Brother Lin's grave.
Shi Keng Yu receives a letter from his fiancée from his hometown, the daughter of the county party secretary, who will be coming to the U.S. soon. The county party secretary has helped the family with a lot of things, and hopes that Shi Keng Yu will take good care of his daughter. Shi Keng Yu was caught in a dilemma, for the sake of the future, he decided to break up with Yaping. Yaping calmly listens to Shi Keng Yu and accepts calmly. After going out, she faints in front of Smail's car. Amazed by Yaping's good looks, Smail uses the excuse of apologizing for bumping into Yaping as a reason for his frantic pursuit of Yaping. A disheartened Yaping agrees to Smail's marriage proposal. When Ruhang learns of Yaping's decision, he advises her that she should know that Smail is a sexual deviant and that marrying such a person is destroying herself, which Yaping does not think.
Ruhang's doctoral defense also started, because of Gordon's obstruction, Ruhang failed to get the degree. On the other hand, Yaping, who is married, suffers frequent sexual abuse from Smail. Yaping sends a stage invitation to Luhang, Shi Kouyu, Smail and their colleagues and friends, inviting them to watch his performance. In the theater, Yaping starts with a folk dance, and when the music turns, she launches into a sensual striptease, with Luhang closing his eyes in pain, Shi Keng-yu grabbing Yaping, and Smail shouting, "You're my wife". The three men wrestled. Yaping drew himself up, changed into a Chinese-style red dance suit, and danced obliviously by the moon lake, eventually collapsing miserably.
The next morning, Lu Hang received the news of Yaping's suicide and was devastated. Ruyu also knows about Ruhang threatening Smail with a gun, so she suspects that the original gun she threw away was a fake gun. Ruhang refuses to admit it, so Ruyu and Gretel go to the lake to fish for the fake gun, and both end up being martyred. Nothing Lu Hang calmly walked into the basement, with flowers throughout the basement, carefully organized their own things, for Ouyang's, for Katie's, for his sister's, after having seen sister-in-law Lin and children, he took the treasured for a long time Pike-style revolver, he took this prince-like pistol, walked into the physics department to pull out the gun, aimed at Shi Keng-yu, Gordon, and Smeir ......
