Lucy is a pawn in a high-society arranged marriage, married off to her playboy husband, Dylan. Then her husband's betrayal, her half-sister's schemes, and her family's indifference push Lucy deeper and deeper into despair. One night, Ethan, a mafia boss and Dylan's half-brother, mistakes Lucy for a "lifelike sex doll." Under Ethan's cold, scorching domination, Lucy wakes up to herself. She knows she has fallen into a web of taboo, revenge, and extreme desire. She decides she will no longer be anyone's sacrifice. She will become her brother-in-law's perfect toy, belonging only to him. With her body and soul, she will personally destroy everyone who betrayed her.
