On a stormy night, set in the early 20th century, a group of members of London's high society are traveling home from a social event and their car gets stuck in the mud in the countryside. They seek refuge in a remote country house. There they are received by the mysterious Uriat and his taciturn mother. Uriat explains to the guests that his mother has the
powers of a medium and can communicate with the dead. Some of the guests are amused and are persuaded to take part in a séance. But when the old woman begins to tell those present details from their own past, the mood quickly changes. It turns out that everyone present carries a dark secret with them and the group is entangled in a web of mutual deception, affairs (including
lesbian affairs) and acts of violence. The hosts are also part of this network, as it finally turns out. As former servants, they were once charged with a double homicide for which those present are responsible, and seek their own justice. == Cast ==
