Cleaner Sarah agrees to a fake marriage with wealthy CEO Daniel to fund her "sister Annie’s" medical bills, unaware Annie doesn’t exist. Torn between ex Matt (who’s manipulating her) and Daniel, their contract marriage spirals into secrets—Daniel hides his real identity as Robin, and they’re monitored by Gigi and Victor, who plot for his company shares. To retaliate, Daniel proposes a real marriage to Sarah. Years later, they renew their vows after defeating the conspirators and unmasking all lies.
