Six university students, all members of Reno Paranormal, embark on an investigation of a "haunted" silver mine in eastern Nevada, seeking explanations for a grisly series of deaths and disappearances in the vicinity, spanning eight decades. Some of the team are skeptics, others have experience with paranormal forces--but none are prepared for the horrible secret they find underground, in the depths of the Silver Princess. Fighting for their lives to reach daylight and freedom, who will live, and who will join the mine's legion of ghosts?
