Marina works at a warehouse for the minimum wage of 951 yen an hour because her husband's low income has left the family struggling. She and her husband do everything they can for their beloved son, but mounting bills tempt her to steal company goods. Warehouse manager Oki catches her and offers to keep quiet if she takes on a “side job.” To protect her family, Marina gives him her body. Rumors soon spread through the warehouse that she will get men off for 951 yen, marking the start of her degrading labor as the workers' sex slave.
