David 'Tool' Roney is a dangerous man with a moral code. Stuck in brutal Parchman Maximum Security Prison in Mississippi, doing life for armed robbery, and abused by his guards, he is consumed by only one thing - escape. His plotting pays off, and together with two other inmates he breaks free. But escaping and staying free are two different things. Tool hits the road with only one thing in mind - to return to the prison and to take vengeance on his tormentors. Payback is a motherfucker. That's Tool's Law. But then he meets a girl called Rose.
