Zak Bagans hosts a show that goes to a different haunted location every week to pit two teams of amateur paranormal investigators against each other to see who can do the best job investigating during a four hour period. Both teams are given the same equipment to use and monitored by remote video feeds. In addition to Zak, there is one regular judge--the ever funny Dave Schrader--and two guest judges each week. Billy Tolley aids with the judge's data analysis and provides technical expertise.
