When the Cassidy-Shaws' autonomous minivan collides with an oncoming car, seventeen-year-old Charlie is in the driver's seat, with his father, Noah, riding shotgun. In the back seat, tweens Alice and Izzy are on their phones, while their mother, Lorelei, a world leader in the field of artificial intelligence, is absorbed in her work. Yet each family member harbors a secret that implicates them in the accident. Noah tries to hold the family together as a seemingly routine police investigation jeopardizes Charlie's future. Alice and Izzy turn strangely furtive. And Lorelei's odd behavior tugs at Noah's suspicions that there is a darker truth behind the incident.
