Dead Mary

Kim and her boyfriend Matt have just broken up, but they travel together to a cottage nearby a lake to spend the weekend with their friends. One of them suggests them to play "Dead Mary" and summon the evil witch repeating her name three times in front of a mirror with a candle. Along the night, Matt hears weird noises, is killed and returns to life, while part of the group is possessed by the fiend. Without knowing who is possessed, the rest of the group fights to survive.
