Energetic and ambitious Kate painstakingly builds the perfect life, but the birth of a second child with serious developmental issues shatters all her plans… After five years of torment, exhausted and internally broken, Kate realizes she has no more strength—and… runs away from her family across the ocean, to Los Angeles. Her husband, Andrew, is left behind to care for their disabled daughter and problematic son, relying on the help of Kate’s closest friend. Fifteen years pass, and Andrew publishes a book about his daughter’s incredible story—how, despite everything, she learned to communicate with her family. Meanwhile, Kate’s new husband, a Hollywood producer, decides to make a film based on the book—meaning the runaway mother will have to face her past again.
