Mansion of the Living Dead 1982

Four strippers take a vacation and wind up at a Spanish resort complex that, despite the hotel receptionist's claims of it being fully booked, appears to be completely empty. After one of the girls mysteriously vanishes and another ends up dead in the pool, both accompanied by the tolling bell from a nearby monastery, Candy and Caty must try to solve the mystery that seems to involve the Spanish Inquisition.
