A miracle by Eddie Lane (Aaron Paul) went viral, and Meyerism has grown exponentially across the world. As the new Guardian of the Light, Eddie is forced to face the question of whether he can grow the movement without becoming a cult leader. Cal (Hugh Dancy) is haunted by dark demons from the past and must come face to face with them in order to defeat them. Sarah (Michelle Monaghan) questions her faith and in looking outside the movement for answers, she may discover one of Meyerism's deepest secrets, and the one person who could put an end to it all.
