While searching for a home for her future husband and herself, Gwenda Halliday is instinctively drawn to a particular house in the picturesque seaside village of Dilmouth. It turns out that her "perfect" house has a terrible past, which Gwenda is forced to confront as she suffers a disturbing case of deja vu. When Gwenda's flashbacks turn to recollections of murder, it's time to consult Miss Marple. The cast includes Sophia Myles (Underworld) as Gwenda, Geraldine Chaplin (Doctor Zhivago), Aidan McArdle ("Einstein's Big Idea") and Paul McGann ("Our Mutual Friend").
