Kim Stanley gives a compelling Oscar-nominated performance as an unbalanced medium in writer/director Bryan Forbes's engrossing and imaginative drama. She orders her browbeaten husband (Richard Attenborough) to kidnap a wealthy industrialist's daughter so she can enhance her reputation as a spiritualist by "finding" the youngster. The tension screws are chillingly turned when Attenborough realises his wife will go to any lengths to achieve celebrity status. Using a purposely sombre atmosphere, Forbes skilfully conjures up suspenseful uncertainty as the ghastly implications of Stanley's plan unfold.

Working-class British housewife Myra Savage reinvents herself as a medium, holding seances in the sitting room of her home with the hidden assistance of her under-employed, asthmatic husband, Billy. In an attempt to enhance her credibility as a psychic, Myra hatches an elaborate, ill-conceived plot to kidnap a wealthy couple's young daughter so that she can then help the police "find" the missing girl.
