Twin brothers, one a Shaolin disciple and the other a bandit, trade places and confuse their respective pursuers.

Two identical twins, the younger one, a Disciple of Shaolin who's crafty tricks make up for his poor kung fu, and the elder, a vicious bandit with tremendous kung fu skills, cause havoc when they mix their identities to fool the Shaolin monks and a ruthless robber, who are both keen to catch the twins for different reasons.

Hsia Hu sneakily graduates from the Shaolin Monastery without completing his required training. During his first encounters with people outside the monastery, Hsia Hu realizes that people are mistaking him for his twin brother, Hsiao Fu, who happens to be a criminal and an expert in the art of Kung-Fu. He is now treated with respect as well as fear and is taking advantage of his mistaken identity. His fun comes to a halt when he is confronted by Yi Lan, a former accomplice turned enemy.
