Agatha Christie's classic sleuth, Miss Marple (Geraldine McEwan), takes on another case of murder most foul. When Tommy (Anthony Andrews) and Tuppence (Greta Scacchi) visit an elderly aunt in Sunny Ridge nursing home, Tuppence is concerned by one resident, Mrs Lancaster (June Whitfield), who rambles about a dead child behind the lounge fireplace. When Tuppence is introduced to one resident's friend, Miss Marple, she finds herself joining forces with her to follow the clues which lead them to the Norfolk village of Farrell St Edmund where there they find a community guarding a number of deadly secrets.
