Seance on a Wet Afternoon (1964)

Working-class British housewife Myra Savage (Kim Stanley) 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 (Richard Attenborough). 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 (Judith Donner) so that she can then help the police "find" the missing girl.
