Adaptation of Tom Perrotta's novel about life in a small town after many of its residents vanished in a Rapture-like event. In the third season, the Garvey and Murphy families come together as they desperately grasp for a system of belief to better explain what defies explanation. The world is crackling with the energy of something big about to happen, a corresponding bookend to the Sudden Departure that sent them all spinning years earlier, bringing their journey Down Under.
