When they discover a boy believed to be dead, the two of them find themselves at the center of a conspiracy of silence that holds answers about the blackout. As the ruthless close in and society continues to collapse, Colby enters a post-apocalyptic battleground where he vows to keep the boy safe as they seek to unravel the mystery of those who want to keep him silent.
