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, implicating them each in the accident. During a weeklong recuperation on the Chesapeake Bay, the family confronts the excruciating moral dilemmas triggered by the crash. 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 -- suspicions heightened by the sudden intrusion of Daniel Monet, a tech mogul whose mysterious history with Lorelei hints at betrayal. When Charlie falls for Monet's teenaged daughter, the stakes are raised even higher in this propulsive family drama that is also a fascinating exploration of the moral responsibility and ethical consequences of AI.
