Supernatural Season 4

Supernatural takes viewers on a terrifying journey into the world of the unexplained. Sam and Dean Winchester lost their mother to a mysterious and demonic supernatural force. Subsequently, their father raised the brothers 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 wherever they go - and battling their own demons that live within.
