Elisa and her friend Britta have won a Cruise in the Caribbean holiday. Right from the start, Britta is thrilled, but Elisa thinks the crew members with their permanent grins and green fitness cocktails rather strange. At night time, she watches the passengers as they slip along the corridors, muttering. She finds out that the ship is sailing in the wrong direction. And then, there’s the dead body… Elisa is convinced that the crew is involved in these strange developments. What can they be planning for the passengers? Soon all becomes clear: this dream ship is really a nightmare cruise!
