All over the world, people's loved ones are returning from the dead. Exactly as they were before they died. As if they had never left. As if it's just another ordinary day. Jacob Hargrave tragically drowned over forty years ago. Now he's on his aged parents' doorstep, still eight years old: the little boy they knew they'd never see again. As the family find themselves at the centre of a community on the brink of collapse, they are forced to navigate a whole new reality and question everything they've ever believed. No one knows how or why this mysterious event is happening, whether it's a miracle or a sign of the end. The only certainty is that their lives will never be the same again.
