Are you ready for the lockdown? Ghost Adventures crew -- Zak Bagans, Aaron Goodwin, Billy Tolley, and Jay Wasley -- is back to investigate the scariest, most notorious, haunted places in the world. The trio will interview eyewitnesses and historians at each location, arming themselves with the stories of the ghosts they will later provoke and confront during their dusk-to-dawn lockdowns. (Note: They don't always come out unscathed!) Then they'll review and analyze their findings with some the most respected experts and specialists in the paranormal field.
