Prague Rising (2000)

On a stormy night, two brothers and their friends come together to explore what is rumored to be a haunted house. They're spending the night there in hopes of solving the mystery that surrounds it. Legend is that centuries ago two Franciscan monks disappeared there after they were discovered to be gay lovers. Now the two monks haunt the residence. Behind a locked door, the ghosts of the monks emerge from their deep sleep. Awakened by the guests, they decide to venture out and begin to roam the rooms.
