The daily life of a couple who have fallen into a rut has grown somewhat lonely, and Erika feels a faint sense of unease about her relationship with her husband. One day, she notices that her freshly hung laundry has suddenly gone missing, and something clicks in her mind. That evening, as she's bringing the laundry back into the room, a suspicious man lurking on the balcony suddenly attacks her. Forced to submit, mentally and physically cornered, Erika finds her body growing wet and aroused, awakening to sensations she'd never acknowledged. Being violated by a man other than her husband transforms her into a sexual slave. Where will this fate ultimately lead her?
