Cave of the Living Dead

"In this lively horror film, a number of young women have mysteriously vanished and now Inspector Doren is assigned to find them. He goes to the village where the seven murdered maidens lived and ends up assisted by the town witch who leads him to a strange laboratory located in the deepest dungeons of an abandoned castle, where they find the blood-chilling solution to the mystery: the slain women have been rendered undead by their ruthless bloodsucking master, a psychotic professor."
