Sienna, a jewelry designer, returns to New York with her twin children. No sooner has she landed than she is humiliated and professionally sabotaged by her ex-fiancé Caleb and his new partner Vanessa. Caleb’s uncle Dominic, CEO of Sterling Group, notices the children’s striking resemblance to his younger self and repeatedly shields them. To fend off family marriage pressure and protect the kids, he enters a one-year contract marriage with Sienna. Once inside the wealthy household, Sienna wins the old matriarch’s favor with her design talent and stumbles upon her late mother’s final design testament. When Vanessa dredges up an old hotel incident from five years ago to confront her at a family banquet, Dominic exposes the inconsistencies on the spot and launches a full investigation. As Sienna shines at industry reviews and gains peer admiration, Dominic grows jealous. Together, they navigate schemes to frame her and guard their children amid an uncertain tug-of-war.
