A wild west town in 1959 Indochina is controlled by Vietnamese warlords and European war criminals. Den-Dhin-Chan Labor Camp is run by four such dangerous men. Here, at the worst prison in the land, European, former-champion boxer Martin Tilman has made a name for himself fighting tournaments on which wealthy criminals gamble in high stakes events. Tilman is due for release, but the corrupt forces running the jail will do everything in their power to keep him locked down. When all that Tilman holds dear is taken away in a vicious act of violence, he is forced to confront the five men responsible and take his revenge.
