Detrás de la puerta (Beyond the door III)

Shy American college coed, Beverly Putnic, has been invited to go on a class trip to a remote part of Yugoslavia to witness and take part in an ancient cultural rite. But what Beverly doesn't know is that she's actually being lured to Europe in order to be made the bride of Satan! Narrowly escaping from the clutches of a witch, Beverly and her classmates take refuge on a train. Unfortunately, black magic meets them at every turn as the train becomes possessed and begins offing them one by one. (Vinegar Syndrome)
