Seance on a Wet Afternoon (1964)

Myra and Billy Savage are a married couple living in London. Myra works as a medium, who holds weekly meetings, séances, for a regular group of customers, while Billy supports her in these ventures, as he does not otherwise work, due to his asthma. "Arthur" is her spirit guide, who was their stillborn son.

Myra is the dominant in the couple, Billy, the weak-minded follower. Myra, with Billy's support, devises a scheme to raise her public prominence as a medium: kidnap Amanda Clayton, the young daughter of a wealthy couple, and using her psychic powers provide information to the Claytons and the police of Amanda and the requested ransom money's whereabouts. Myra and Billy view this scheme as a victimless crime, if a crime at all, as they don't plan on harming Amanda, and they are returning the requested ransom. To carry out the scheme successfully, they will have to: kidnap Amanda; convince Amanda that her temporary captivity is not out of the ordinary, while having her not be able to identify them; insert Myra into the case of Amanda's kidnapping, her information which will be the key to finding Amanda and the money; and return Amanda and the money without having either traced back to them. Beyond these logistics, Myra and Billy themselves will factor into how the plan works. Myra may have either conscious or subconscious thoughts on what she wants to do, in her belief that she truly does have the power.
