The TV show "Supernatural"

Supernatural tells the story of Sam and Dean, two brothers bound by the same destiny. They travel through the emptiness of the American plains on a mission to find and kill the most terrifying creatures of darkness, known to people only through legends and superstitions. During this struggle against evil, Sam discovers paranormal abilities: his strange visions foretell the deaths of those around him and approaching dangers. Encouraged by their father to begin this adventure and find the creature that killed their mother years earlier, the brothers launch a hunt for demons. Vampires, werewolves and ghosts are just some of the creatures Sam and Dean face.
