Wealthy Mr. Donovan secures a private hospital suite for his newborn daughter Isabella. Sixteen years later, as his company gears up for a merger, he pushes his daughter’s fiancé Adrian—who needs a kidney transplant—to stay loyal. When Isabella proves incompatible, Adrian asks cleaner Elena for a test; she resists but complies, only to learn she’s not his match.
An investigation uncovers a shocking hospital mix-up: Elena is Mr. Donovan’s biological daughter, while Isabella is from the Martinez family. Enraged at losing her identity and family, Isabella hires a hitman to kill Elena. But on the eve of Elena’s wedding to Donovan, he stops Isabella from carrying out her revenge. In the end, the feuding women reconcile, embracing their new bond as sisters and toasting a fresh family start.
