In his apartment, Stanley's loyal partner, his pet dog Milo, found the atmosphere in the room strange, but Stanley found it was a mask. He picked up the mask and observed it carefully. Suddenly, when Stanley's face approached the mask, the mask stuck to Stanley's face. After a crazy whirlwind, Stanley became a green-headed monster with super magic. Only one white tooth stands out. He retaliated against people who looked down on him in the past and played all kinds of practical jokes to tease others.
Under the magic of the mask, Stanley also robbed a bank and sang and danced with his beloved Tina at the Palm Club, which attracted the jealousy of the gang leader and the attention of the police, but it was difficult for others to catch him. Dorian, the leader of this gang, knew the magic of the mask and designed to take it away, while Stanley was put in prison. After a scuffle, kind Stan used his wisdom and courage to defeat the evil enemy, and he and Tina finally got married.
