David Siu and Danny Cheng were originally good friends. After a family incident, Danny came to help. One day, David was brutally beaten by thugs. Fortunately, Danny passed by and saved him. Later, David asked Danny to teach him martial arts. He progressed rapidly but often injured his fellow students. The master had no choice but to painfully sever the teacher-student relationship. Afterwards, David encountered his enemy and severely beat him to vent his frustration. Because of this, he was hired by a mafia boss as a hitman, while Danny became a detective.
