Following the release of the Darkness, this season follows the Winchesters and their allies as they find themselves fighting the most powerful supernatural entity they've ever faced.

The Creepy. The Demented. The Unexplained. The Unearthly. Sam Winchester grew up hunting such terrifying things. But that’s all past. Law school beckons him. So does safety and normalcy. That is, until Sam’s estranged brother Dean appears with troubling news: their father has disappeared, a man who’s hunted evil for 22 years. So to find their father, the brothers must hunt what their father hunts…and Sam must return to the life he’d rather leave behind.
