Husband requests an investigation after hearing rumors that his wife is secretly watching their sex videos during girls' nights, so a hidden camera is set up in the living room. In the room where the gathering takes place, young married women begin drinking alcohol and sharing their private sex recordings with one another. Conversations quickly turn shockingly explicit, with comments like "I'm sick of instant noodle sex that doesn't last more than three minutes!" As the alcohol flows, the situation escalates beyond imagination.
