Teenage Ghost Girl 1984

More or less a Thai version of The Exorcist. A couple and their young daughter move into an old, remote house. Bones are found in the attic where strange noises are heard and the creepy voyeuristic caretaker (who spies on the family through hidden passageways) calls for an evil spirit that thrives on virgin's blood. The daughter is finally possessed, speaks with a male voice, develops extreme strength and goes on a rampage.
