After narrowly escaping the chaos of the "Siege of Jasons," physicist Jason Dessen (Joel Edgerton) and his wife Daniela (Jennifer Connelly) have fled with their son Charlie to a parallel world that finally feels safe — but that fragile peace won't last. As Jason's obsession with the Box deepens, Daniela's paranoia threatens to tear the family apart from within. Meanwhile, Amanda (Alice Braga) and Ryan (Jimmi Simpson) join forces in a desperate bid to find their way home, while the ambitious Leighton (Dayo Okeniyi) relentlessly pursues his vision of a perfect world. Season 2 is an original story, taking these characters into uncharted multiverse territory that no book can spoil.
