A raw documentary experiment follows Karen for 24 hours to see how far her sexual arousal can be pushed. She is watched while eating, applying makeup, showering, and sleeping, and a cock penetrates her whenever she lets her guard down. Told only that she was attending an overnight shoot, Karen is kept in near-confinement and fucked seven times in a single day. Her protests about the timing, mood, and circumstances are ignored as the attacks continue anywhere and at any moment. It becomes a full day of sex she says she will never forget.
