When Joe and Danny take on Mrs. Snowden's housework, they don't know that they won't be alone in the house. Inside the walls lives a creature that is equal parts ghost, succubus and witch, and it uses the mansion as a prison for souls. Now, as the October moon falls over the mountains, she is ready to rise and reclaim her flesh. Kayla is in love with Joe, so when he asks her to come to a party at his house, she accepts his invitation. But once they get there, strange things begin to unfold. People disappear, a mysterious dog appears, and then the boys begin to change... The ghosts warn Kayla to save her friends before they are consumed by a seductive witch. But she needs to hurry. As Halloween approaches, the house becomes a vessel for the dark magic of Black Rock Mountain, and the shadows that rule the forest return home...
