Hana lives with her sick mother, who is weak and in poor health. They have been falling behind on rent payments, so Hana asks the landlord, who uses a wheelchair, to let her work as a helper. However, the landlord takes advantage of Hana's words, 'I'll do anything,' and makes her help with his sexual desires. Hand jobs, paizuri, fellatio—the demands escalate, and one day he even forces her into unprotected sex. As Hana indulges in the landlord's perverted tastes, she discovers female pleasure and falls into the abyss of being a sex slave.
