Overview
Prison on Fire is a 1987 Hong Kong prison film directed by Ringo Lam and starring Chow Yun-fat and Tony Leung Ka-fai. Yiu (Tony Leung Ka Fai) is a young advertising executive in Hong Kong. One night, defending his father from attack, he accidentally shoves a street thug in front of a bus. Sentenced to three years in prison, Yiu is "fresh meat" for the hardened criminals and triad stooges that run things, and is preyed upon by sadistic guard Scarface (Roy Cheung). The virtuous Ching (Chow Yun-Fat) befriends Yiu and becomes an ally. A sequel, Prison on Fire II, was released in 1991.
Plot
The advertising designer Lo Ka-yiu is sentenced to three years of imprisonment in a Hong Kong prison for manslaughter. He was convicted for pushing a man who had robbed the grocery store of his father onto a street under a passing bus.
He is assigned for work at the prison ward where he meets Chung Tin-ching. The men befriend each over and Yiu asks to be transferred to the laundry where Ching is working. Yiu observes how a member of the gang of triad boss Micky steals scissors from Ching (to use them as a weapon). Yiu notifies Ching who manages to get the scissors back, but as a consequence Yiu gets bullied by the triad members.
