Former hitman Ginya Yabuki (Riki Takeuchi) left the mafia and split somewhat contentiously with his longtime former partner. Years later, that same ex-partner has emerged as the head of a very dangerous crime syndicate and Yabuki is forced to confront his former partner, which may start an all-out war within the Tokyo Mafia.
Hard man Ricky is incarcerated in a futuristic prison where ultra-violence is his only means of survival in the corrupt, sadistic system. He must battle his way quite literally 'through' the feared 'gang of four', and undergo multiple tortures before facing the governor in one of the goriest climaxes ever seen.
