An unarmed man wakes up to find himself locked in a tiny, cramped unlit concrete space, in which he can hardly move. Why is he there and where did he come from? All we know is that he has a terrible stomach injury and is slowly bleeding to death. He begins to explore the narrow confines of his maze-like prison. Horrible visions of hell wait for him at each end of the space! Horror from director Shinya Tsukamoto (Hiruko and Tetsuo).
