From visionary director Ngai Choi Lam comes a ferocious, action-packed tale of corruption, vengeance, and unrelenting violence, now presented in a brand new 4K restoration. Wrongly convicted of manslaughter, martial arts master Ricky (Louis Fan) is thrown into a nightmarish penitentiary where sadistic wardens rule and the inmates are locked in a constant battle for dominance. Facing monstrous opponents and unimaginable cruelty, Ricky must unleash the full force of his power to stay alive and strike back against a system designed to break him.

Adapted from the cult Japanese manga by Masahiko Takajo and Tetsuya Saruwatari, this explosive classic blends the raw intensity of legendary prison dramas with the bone-crunching fury of Hong Kong action cinema, delivering a truly unforgettable, no-holds-barred experience.
