Sam and Dean double their efforts to find a cure for the Mark of Cain, after the massacre at the ranch. Meanwhile, Rowena plots against Crowley, and Castiel tries to mend his relationship with Claire, who is bent on revenge against Dean for killing her friend.
Supernatural follows Sam and Dean Winchester, two brothers bound by tragedy and blood to the one thing that runs through both their veins – hunting monsters. Dean and Sam have faced insurmountable obstacles: Sam returned from Hell without his soul, and Dean risked everything to get it back for him. The power struggle between good and evil raged on, with the new King of Hell, Crowley, ultimately emerging as their adversary. Shockingly, Crowley had made a secret deal with Sam and Dean’s closest friend, the angel Castiel, who is now a desperate freedom fighter on the losing side of a post-apocalyptic civil war in heaven. Together, the uneasy allies sought to open a door to purgatory, where a great untapped well of souls lies waiting to be used as the ultimate form of military power.
