S03E13: 'Ghostfacers'

Sam and Dean take a break from their usual gig to star in a gritty reality show called Ghostfacers, which chronicles the pursuit of the paranormal.

Ed Zeddmore and Harry Spengler have created a radically different and sometimes violent show full of profanity that takes them to the Morton Mansion, an abandoned estate which becomes one of the most haunted places in America one night each year.

However, as their team begins to be picked off in a grisly manner not fit for television, they realise they are in over their heads.
