When Deena learns the truth, she's devastated, heartbroken-and mad. After unexpectedly running into him several months later, she comes up with an on-the-spot plan of revenge to pay him back and tells him she had been pregnant by him when their relationship ended. She makes him believe she's given birth to his child which happens to be her best friend Angie's newborn son, Aaron. After Shawn develops an unconditional fatherly love for him, Deena finds it harder and harder to reveal the truth. Her best friend is reluctantly forced along for the ride, and both women live on edge to keep the truth from coming out.
