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.
Supernatural celebrates its 200th episode. When Sam and Dean investigate the disappearance of a teacher, they are stunned to discover that the school is putting on a musical based on their lives. Familiar faces abound in this milestone episode.
