A string of mysterious disappearances involving prominent women. At the center stands Nana, CEO of an IT company. Buried in her daily work, she believed herself unconnected to the incidents—until one morning, on her commute, Nana is suddenly abducted. Imprisoned in a dark, windowless cell with no way to call for help, she is left completely helpless. The owner of the slave market appears and tells her, "Think of this place as an auction, like one for racehorses." Powerless, Nana is forced to endure. Finally, the day of the Housewife Slave Market arrives. Just before the auction begins, her husband suddenly appears, setting off an unexpected turn of events.
