Watch 123Movies. In a scorched, post-apocalyptic world, survival is fragile and trust is dangerous. When a hardened loner discovers a naive man with the mind of a child, the two form an uneasy alliance, their journey colliding with a sinister school where the once students (now adults) are still ruled by the authority figures of the past. Fear, secrets, and the threats prevent them from exploring whats beyond their gated community.
