Ten women find themselves in a vacant mansion on Spektor Island in December, 1972. Each believes she's traveled to the house on business, but they all agree that something seems strange. For one thing, the entire house is full of pictures and statues of pigs. The women all come from drastically different walks of life. None of them would have chosen to spend the night together in such an eerie place, but the last ferry for the mainland has just left, and a terrible storm is rolling in. Trying to make the best of an unpleasant situation, they raid the mansion's wine cellar and throw a party. As the night creeps on, however, it becomes clear that someone--or something--has lied to get them in the house. It's not long before someone mentions that Spektor Island is supposed to be haunted. Of course, no one in the house believes in ghosts. At least, not until the first murder.
