Rachel Blum and Andy Landis are just eight years old when they meet one night in an ER waiting room. Born with a congenital heart defect, Rachel is a veteran of hospitals, and she’s intrigued by the boy who shows up alone with a broken arm. He tells her his name. She tells him a story. After Andy is taken back to a doctor and Rachel is sent back to her bed, they think they’ll never see each other again. Yet, over the next three decades, they will meet again and again --- linked by chance, history, and the memory of the first time they met, a night that changed the course of both of their lives.
