Living in a town near Munich, four waitresses at a topless joint decide to take a few days off work to visit the sunny Gran Canaria. Following the travel agency's recommendation, they finally arrive at this dream hotel by the beach, filled with high expectations of having a good time; however, right from the start, the girls sense a strange vibe. Why is this hotel completely vacant, and the beach mysteriously deserted? After the initial disappointment, the secretive director of the hotel, Carlo Savonarola, shows them to their rooms, but soon, the wailing sound of the wind blowing, and the echoes from the empty corridors that bring chills down the spine, will demand answers. Is this situation linked somehow to the grim history of this hotel? What lies hidden behind the thick stone walls of the nearby abandoned convent which dates back to 1749?
