Along with the release of the synopsis, the first episode of "Supernatural" gets a short clip. "Sympathy for the Devil" will pick up where the season 4 finale left off when Dean and Sam watch as the seal is broken and the Devil emerges from Hell.

In the sneak peek, a girl named Becky, who is apparently a fan of Sam, comes to the brothers' motel to deliver an important message from Chuck the Prophet (guest star Rob Benedict). "The Michael sword is on earth, the angels lost it," Becky told Dean and Sam, adding that the sword's location is in a castle on a hill made of 42 dogs. In the synopsis, Chuck also tells them that Castiel has been blown to bits by the archangels.

"Supernatural" returns on September 10. Paris Hilton will guest star in the fifth episode as a demon taking the shape of Paris Hilton. "We wrote the role just for her," producer Sera Gamble said. "We're very excited that she said yes."
