Curt has been beaten, betrayed and brutalized by just about everyone he's known. But six years in prison taught him a lot - including how to force straight cons to "get off" as he uses them, and how that can be a very satisfying method of revenge. Now he's out and trying to stay straight, but problems with his marriage and zero prospects of earning a living make that almost impossible. It's while he's hustling two gay men in a bar one afternoon that he mentions what he's done in prison...and the bet comes up.
It seems those men want a little revenge of their own against someone who's caused them trouble. If Curt can make that "straight" guy "get off" while being assaulted, they'll give him a chance at a new life. Being in the mood to do some damage, Curt agrees and they start laying their plans. But step-by-step, Curt realizes things are getting out of control, and he has no one to pull him back from the abyss. And a stupid little bet is threatening to plunge him headlong into disaster.
