Peggy marries Mark and quickly bonds with his six-year-old son, Ethan, embracing “bonus motherhood” after learning she can’t have children. Mark says Ethan’s mom, Danielle, left and never looked back, and Peggy believes him. Their life settles into a warm routine of school runs, soccer games, and strawberry snacks.
At a match, Peggy spots a new boy, Ryan, who looks exactly like Ethan—same face, same habits. Uneasy, she asks Mark about Danielle and whether there were other kids; he flatly denies it. Peggy tracks down Ryan’s mom, Camille, and the tension in her reaction deepens Peggy’s suspicions.
Cornered, Mark finally admits the truth: Ethan and Ryan are twins. After a bitter divorce and his own spiral, he kept Ethan while Danielle’s sister, Camille, raised Ryan. Later, Camille shows Peggy papers—Mark voluntarily relinquished his parental rights to Ryan. The secret explains the lies, the drinking, and the distance.
The boys soon meet and click instantly, calling each other “me.” Ethan wants Ryan in their lives, but Peggy’s trust in Mark is shattered; she can’t forgive that he chose one son and buried the other. As Ethan still looks at his dad with shining eyes, Peggy is left weighing a brutal question: can she give Mark another chance?
