Now almost two decades later, married with a beautiful son, they are living the perfect suburban life in Middle America. But when a camping accident leaves Maddie badly scarred, she begins attending writing therapy, where she gradually reveals her fears about Ian's PTSD; and the couple's tangled and tumultuous past with Jo.
