Hua (Andy Lau), who has cancer and only four weeks to live, robs a financial company, takes diamonds and holds hostages. He Shangsheng (Liu Qingyun), who has just been transferred as a civilian part-time negotiator, rushed to the scene and tried to persuade Hua to surrender. Hua threatened to play a 72-hour game with him and escape. He Shangsheng was deeply indignant for this. In the process of escape, Hua met a police roadblock, so he held Liang Wanting (Yoyo Mung) as a couple, and managed to escape from danger by hiding his eyes and ears. They met unintentionally, leaving a deep impression on each other.
