The House with No Windows

You and your fellow student are on a weekend field trip with your college professor. The excursion takes you to an old stone house located in the middle of the Adirondack Mountains. The purpose of the trip is to prove that folklore and myths are just that? Then strange things start to occur and you try to escape and there is no way out. The house has come to life and its evil entity needs your soul and blood to feed its dark desires. What would you do to survive?
