The Ghost Adventures crew investigates St. Anne's Retreat, where in 1997 a group of teenagers, drawn to the property for its legends of dead nuns and hellhounds, were held hostage and terrorized by three armed security guards.

The crew travels to Butte, Montana, to investigate a historic bordello where something malevolent lurks inside. As they communicate directly with the aggressive spirits, Zak suffers a mysterious scratch on his neck and loses time during the lockdown.
