Hinako is a beautiful young wife who secretly ran up debts without telling her husband. Desperate for more money, she visits a loan shark even though she still has not repaid her previous loan. The man corners her and says the only option is to film an obscene video and make her repay the debt with her body. Forced to perform in an amateur porn shoot as collateral, Hinako is pressured into claiming it is all her own choice. Once she submits, the man trains her with degrading dirty talk. He then introduces her to a sex-shop owner, promising she can earn even more in the sex industry, and puts her through masochistic erotic-service and dirty-talk sex training until the constant verbal degradation brainwashes her.
