Once a celebrated actress, Go Seon-yeong is now a middle-aged housewife trapped in a life of humiliation—her husband is unfaithful, and her three spoiled sons are nothing but trouble. Desperate for change, she visits a shaman on a friend’s recommendation. The shaman delivers a chilling verdict: "Your husband strayed because you’ve grown old and unattractive. If you want to reclaim your youth, you must form a bond with a young woman." Handed a cryptic talisman, Seon-yeong—consumed by insecurity and rage—misinterprets the "bond" as a sexual relationship. So, when a new live-in housemaid arrives, she ends up sharing a bed with her.
