Liu Yung, co-star of every finished Bruce Lee film, plays a young man who is thrown into jail simply because he displeased a police inspector, but even when he's released, the police persecute him until he has no choice but to become a real criminal. Watch for such action favorites as Ai Fei (The Kung-fu Instructor) and Chen Kuan-tai (Man Of Iron) in this hard-hitting drama, based on an actual investigation that linked second offenses to both the cops and crooks.
