After Dean (Jensen Ackles) is saved from the Mark of Cain, Season 11 of this fantasy-horror series finds the Winchester brothers facing a new enemy that is stronger than any supernatural entity they've ever faced: the Darkness. When Sam (Jared Padalecki) and Dean rush to help a neighboring town as the Darkness takes over and infects the residents, they come across a baby that they risk their lives to protect - only to find out that the baby may not be as she seems. The brothers find themselves partnering with unlikely allies to destroy the Darkness/Amara (Emily Swallow). Under a dog attack spell by the witch Rowena (Ruth Connell), Castiel (Misha Collins) begins to attack others uncontrollably, setting off a manhunt to bring him in. Dean comes face-to-face with someone he thought he'd never see again and it could change everything.
