Helen Miller, an indecent woman by the sisters' standards, checks in to the inn the following day, after which Verónica goes to visit Luis, with whom she is having an affair, and the two have sex.

She goes to meet with a local police chief to tell him of her suspicions, and he reveals that Marta's fiancé had disappeared on their wedding day years before.

The next day, Laura returns to the inn with a local man, Eduardo, posing as her husband who has just arrived, and rents a room.

Meanwhile, during a meal at the inn's restaurant, a woman falls violently ill with food poisoning; her husband notices an odd piece of meat on her plate, and he wraps it in a napkin to give to police.

Meanwhile, at the local police station, it is determined that the piece of meat is in fact a chunk of flesh with an eyeball attached; the body part had been stirred up after Laura's earlier attempt to probe the contents of the vats.

While the police and a band of villagers head to the inn, Laura goes to search for Eduardo, and finds him dead in the sisters' bedroom.

The film received theatrical distribution via Paramount Pictures in Spain, and was released in the United States under the title It Happened at Nightmare Inn.
