Dean (Jensen Ackles) and Sam (Jared Padalecki) investigate several murders at Oktoberfest. The first victim was found with bite marks on her neck, much like a vampire would leave, while the second victim has wounds that look like a werewolf attack.
After a mummy rises from his crypt, Dean determines that a shape-shifter demon is terrorizing the town as iconic monsters from the old Hollywood movies.
Robert Singer directed the episode written by Ben Edlund.
