 Michael Dublin is a full-time con man working the underground boxing circuit. A lonely drifter on the run from a past best forgotten, he moves from one scam to another, leaving a trail of enemies in his wake. Dublin invents his best scam yet when he meets Katherine Paker, a female fighter with the skills to take down a man twice her size. In a scheme Dublin calls "fight-rigging, in reverse", the two hit the road working fights in seedy basement bars, abandoned warehouses, and backwoods county fairs. But Dublin s shady past catches up with them and suddenly the stakes are higher - and more dangerous - than they d ever imagined.
