Dan and Margaret have come to spend Christmas with Rachel and Edmund in their renovated seventeenth-century labourer's cottage. Later, as Rachel plays the piano, she suddenly gets a sinister feeling of déjà vu. Shortly afterwards, the electricity fails and the phone is out of order too. It is the start of a series of macabre events which mount relentlessly to a bizarre and terrifying climax culminating in a tragic report coming from the TV into an empty brightly-lit room.|2 women, 2 men
