S3, E13: Sam and Dean stumble into starring roles on a gritty reality show called "Ghostfacers," which chronicles the pursuit of the paranormal. Ed Zeddmore (guest star A. J. Buckley - "CSI: NY," "The Box," "Entourage") and Harry Spengler (guest star Travis Wester - "Dirt," "CSI: Crime Scene Investigation"), with whom Sam and Dean once had a run-in, have created this radically different show -- full of profanity -- that takes them to the Morton Mansion, an abandoned estate. Once every four years, the mansion becomes one of the most haunted places in America. As the team attempts to document this paranormal occurrence, they begin to get picked off in grisly manner, and soon realize they are in over their heads.
