Tom Kovack (Leonard Nimoy) is a racing driver who begins to have intense visions during a crash. Occult investigator Michelle Brent (Susan Hampshire) thinks he is having a premonition of an American woman in danger in an English county house.
Tom and Michelle track down the house (and thus the woman) and begin to uncover a Satanic plot to possess the woman's, Andrea's (Vera Miles), young daughter Jennifer (Jewel Blanch) for evil means... or just get Andrea's money.
This is a good film, though at times the story is a little disjointed which is probably why it never succeeded as a TV pilot. Remade as a film though the story is solid if a little too light to score as a horror. As a detective drama with a supernatural element it works a lot better. Nimoy and Hampshire had great chemistry together.
