Director Ringo Lam explores potent themes of loyalty, authority, and corruption in this tough-as-nails crime drama set within the simmering confines of a prison. When he is incarcerated for accidentally killing the street thug who attacked his father, advertising executive Yiu (Tony Leung Ka-fai) finds himself thrust into a dangerous world populated by sadistic guards and warring prison gangs. Together with a seasoned convict (Chow Yun-fat) who takes him under his wing, Yiu must learn to fight to survive life on the inside.
