Pregnant Monica Lawson’s world implodes when she walks in on her billionaire husband Ethan Blackwood at a maternity clinic, escorting his mistress to a prenatal appointment. Heartbroken and furious, she storms out that same night — but Ethan’s head bodyguard, bribed by the other woman, kidnaps her, locks her in an abandoned warehouse, and sets it ablaze to erase her for good. Five years later, a sharp, mysterious woman named Cathy steps back into Ethan’s life.
