This is an early onscreen collaboration of Jackie Chan, Sammo Hung, and Yuen Biao. Muscles (Chan) and Ricky (Biao) are two cops who go after a corrupt cop with ties to the Japanese underworld. When Ricky is kidnapped, Fastbuck (Hung), a childhood friend of Muscles, recruits some of their old orphanage friends, now small-time criminals, and this unlikely group goes to the aid of the cops to fight the mob. ~ Jonathan E. Laxamana, Rovi
