Things go terribly wrong for five college students out to prove the existence of the paranormal. No place is more haunted or terrifying than the infamous Odenbrook Sanitarium, a facility shuttered after a mass suicide forty years ago. Thrills turn to nightmares as members of the group go missing, cellphones mysteriously vanish and something begins setting off EMF sensors throughout the structure.
With communication to the outside world now impossible and maps of the facility becoming increasingly inaccurate the group bands together and heads for the exit. Corridors turn into mazes, flashlights fail, walls appear where the doors once stood and something seems to be hellbent on leading the group to the bowels of the building where a horrific fate awaits in this hair-raising, scare-filled thrill ride.
