After her father left home, Anna lives alone with her sick mother. When she finds out that her rent is behind, she decides to work as a home helper for her landlord to ease her mother's burden. Taking advantage of Anna's pleas, saying "I'll do anything," her landlord, who is wheelchair-bound, begins to sexually harass her repeatedly. At first, he only provides care, but his demands escalate, and he even ends up having sex with her and ejaculating inside her. Anna resists at first, but gradually becomes his sex slave.
