Kazuki Shima

Yoshioka (Tatsuya Nakazawa), imprisoned for killing a yakuza boss, and Kubota (Koki Tora), jailed for murdering his own father, are sent to a prison island where only death awaits. No sooner do they arrive than they are given a hellish “welcome” by the warden, Nakano (Yoshiyuki Yamaguchi), before being thrown into a communal block filled with dangerous inmates. There, they learn of a brutal underground fighting arena— groin strikes, eye gouging, biting… anything goes. Can the two survive long enough to escape the island alive? A high-octane, brutally real battle movie, where pride and fists collide, is born.

Legendary yakuza actors Hakuryu and Hitoshi Ozawa star in this epic series where money, power, and brutality fuel turf wars across the land.
