The crew continues their quest to unravel supernatural activities across the country, and this time deep into the Nevada desert, they try to solve the secrets around of the plane crash that led to the death of movie star Carole Lombard, the lethal murders of Paul Coski and other cowboys who cheated at cards during poker games. And in their celebration for Ghost Adventure's 100th episode, they heads to the "Exorcist House" - the inspiration for movie "The Exorcist" in the St. Louis area and engage in the lock down to search for the real life demon(s) that possessed a 13-year-old boy on March 16, 1949.
