A group of holidaymakers head for the Spanish resort of Elsbels for a 4-day visit. When they get there, they discover that the hotel is still being constructed and that something is strange about the staff: they all look very similar. To top it all off, the weather seems to be having an adverse affect on the Hotel's foundations.—Simon N. McIntosh-Smith
