Twenty-three years ago, Sam and Dean Winchester lost their mother to a mysterious and demonic supernatural force. Subsequently, their father raised them to be soldiers. He taught them about the paranormal evil that lives in the dark corners and on the back roads of America... and he taught them how to kill it. With their father gone, Sam and Dean are now facing an all-out demonic war.
As they work to stem the rising tide of demonic activity, they continue to travel the country, battling the supernatural - changelings, cursed objects, vampires, witches, malevolent spirits, even a very un-merry Anti-Claus - wherever they go. Dean's clock is ticking, with Hell awaiting him in less than a year's time. And Sam still faces the fallout of a slain demon's plan to make him the leader of the gathering demonic army.

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.
