The Magnificent Seven

S3, E1: In the third season premiere, bracing themselves for the possibility of an apocalyptic war, Sam and Dean realize they have an enormous task: hunting down the hundreds of demons that escaped from the Devil's Gate. Dean decides to live life to the fullest and exhibits a carefree attitude that troubles Sam, who is trying to find a loophole in the deal. Meanwhile, fellow demon hunter Bobby (recurring guest star Jim Beaver) tells the brothers about a sighting in Nebraska that turns out to be seven demons that are manifestations of the seven deadly sins.
