In December 1926, best-selling mystery writer Agatha Christie suddenly vanishes, leaving her husband Archie with no clue as to her whereabouts. After ten days, she is discovered by a journalist staying in a hotel in Yorkshire under a false name. Subsequently she remembers (or claims to remember) nothing about her activities during this time. She visits a psychiatrist, who uses hypnosis in an attempt to get to the bottom of her apparent amnesia. She tells him about her early life: her middle-class childhood, experiences during World War One and courtship by the charming but faithless Archie. - IMDB
