It seems, next season will be the hard season for The Winchester brothers. Harder than dealing with Lucifer? Well, if you read the official description that was released by The CW, it seems yes. Supernatural Season 7 premiere is on Sept 23rd. Here, the official description:
Returning for its seventh season, this haunting series follows Sam and Dean Winchester, two brothers bound by tragedy and blood to the one thing that runs through both their veins - hunting monsters. This past season, Dean and Sam 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 lie waiting to be used as the ultimate form of military power.
Sam and Dean reeled from the betrayal by their friend - and raced to stop the angel and demon before they opened that dangerous, otherworldly door. Now, in season seven, the Winchesters will find themselves in an increasingly sinister, changing landscape, up against a new foe unlike anything they've ever fought. They'll find their old tricks, weapons and hiding places all rendered useless. All they'll have is each other. And the certainty that, like the last of the cowboy outlaws, whatever they face, they're not going down without a fight.
The series stars Jared Padalecki as Sam Winchester, Jensen Ackles as Dean Winchester and Misha Collins as Castiel. SUPERNATURAL is from Warner Bros. Television in association with Wonderland Sound and Vision, with executive producers McG ("Charlie's Angels," "The O.C."), Eric Kripke ("Boogeyman"), Robert Singer ("Midnight Caller"), Sera Gamble, Ben Edlund, and Phil Sgriccia.
