When film producer
Willie Chan left the Lo Wei Motion Picture Company to join
Golden Harvest, he advised
Jackie Chan to decide for himself whether or not to stay with
Lo Wei. Chan began work on the film, but then broke his contract and joined Golden Harvest. This prompted Lo to blackmail him with
triads, and to blame Willie Chan for his star's departure. The dispute was resolved with the help of fellow actor and director
Jimmy Wang Yu, allowing Chan to stay with Golden Harvest. In order to complete the film, Lo hired stunt doubles to take Chan's place in the remainder of the film, and used alternative takes and reused footage from the first film. Chan mentions that the end product of the film was so bad that he even tried to stop it from being released by going to court, but Lo released the film regardless. Was released at the peak of the triads running the Hong Kong movie business. ==Plot==
