Isabella Albert, the long-lost true heiress of the Albert family, was pushed down a hillside as a child by the adopted daughter Lizzie and later adopted as Chloe Murphy. To pay for her adoptive mother's hospital bills, she works as a bunny girl in a bar—and accidentally spends a night with drugged Mafia godfather Damon Rizzo. She refuses his money, tucking five dollars into his collar as a tip—and ends up pregnant with quadruplets. Damon initially mistakes her for a gold-digger, hurting her with harsh words. Chloe hides her pregnancy and works at Rizzo Group to survive. As she saves the elderly matriarch from an ambush, DNA confirms Damon is the father, and the truth about the auction-house kidnapping and Chloe's origins emerges. Damon shifts from wounding her to protecting her fiercely. Lizzie's schemes are exposed, the old crime of the true heiress being pushed down the hillside comes to light, and Chloe's butterfly birthmark and DNA truth reunite her with her biological mother. Lizzie is expelled and punished.
