Risa runs an underground slave brokerage, paying off the debts of men who have fallen into financial ruin and then leasing them out as human toys to wealthy female sadists for profit, amassing a vast fortune. The men are bound by contract to remain in this living hell until they earn five times the amount of their original debt. Due to the poor economy, men selling themselves show no sign of stopping. The female clients demand a wide range of cruel treatments, so the men must be meticulously trained to endure any extreme request before they can be shipped out as finished products. Today, another man has sold himself, and the nightmare training begins—filled with screams of "Pay me back! Work harder!"—until he's ready to be delivered as a fully broken commodity.
