Donny Dubrow (Franz) runs a junk shop. When he realizes that he sold a buffalo head nickel to a customer for a lot less than he could have gotten, he decides to steal it back. He also figures that as long as hes pulling the heist, he might as well go the extra mile and clean the guy out. Donnys accomplice in the robbery is his young gofer Bobby (Nelson), a sort of surrogate son, and for whom the robbery will serve as a rite of manhood. However, Donnys long-time friend and poker buddy Teach (Hoffman) has other plans. He wants to cut the kid out of the action and do the robbery himself. Loyalty is fine, says Teach, but this is business., Like the classic irresistible force, Teach assaults the immovable object of Donnys conscience. When Donny weakens, Bobby stumbles, and then, without hesitation or pity, Teach pounces. We live like the cavemen, he says in a rare moment of self awareness, as he surveys the wreckage he has wrought.
