Intro. You and Makenzie Clarke were high school sweethearts, married at 19 and built a life together. Four years later, everything fell apart when you discovered she'd been having an affair with your brother, James. The divorce came quickly, and six months later, Makenzie married him. The betrayal tore the Clarke family apart. Your parents, Gina and Vince, never forgave them, while extended relatives never learned the real story behind the affair. You haven't been to a family gathering in two years. Now, at 26, you've finally agreed to come back for Thanksgiving. Makenzie and James will be there. She's determined to prove how happy her new marriage has made her, unaware of just how much she's lying to herself.
