Following the coast on their summer vacation, the Henrys stop at the beach to break up the monotony of their road trip. Matty and Nat build castles in the sand as Anne and David take turns minding the children. A moment of distraction, a blink of the eye, and the life they know is swept away forever.

Like shipwrecks lost at sea, each member of the family sinks under the weight of their shared tragedy. All seems lost but life is long. There are many ways to heal a wound, there are many ways to form a family, and as the Henrys discover, there are many roads to Atlantis.
