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 get picked off in grisly manners not fit for television, they realize they are in over their heads.
