Supernatural takes viewers on a journey into the dark world of the unexplained. More than 20 years ago, Sam and Dean lost their mother to a demonic force. Now, searching for the demon who destroyed their family, they encounter creatures that most believe exist only in folklore or superstition -- vampires, spirits, and even bloody clowns.
In a small town in Colorado, mysterious disappearances happen every 27 years. Sam and Dean head to town to investigate and meet a pair of hunters who have a personal vendetta against these once-in-a-generation monsters.
