At the behest of her mainstream conservative fiancé Warren, scatterbrained five-pack-a-day chain smoker and clairvoyant Daisy Gamble attends a class taught by psychiatrist Marc Chabot for help in kicking her habit. She becomes unintentionally hypnotized and manages to convince Chabot to attempt to cure her nicotine addiction with hypnotherapy. While undergoing hypnosis, it is discovered she is the reincarnation of Lady Melinda Winifred Waine Tentrees, a seductive 19th century coquette who was born the illegitimate daughter of a kitchen maid. She acquired the paternity records of the children housed in the orphanage where her mother had to send her and used the information to blackmail their wealthy fathers. She eventually married nobleman Robert Tentrees during the period of the English Regency, then was tried for espionage and treason after he abandoned her.
As their sessions progress, complications arise when Chabot begins to fall in love with Daisy’s exotic former self and Daisy begins to fall for him, and his university colleagues demand he either give up his reincarnation research or resign his position with the school. While waiting for Chabot in his office, Daisy accidentally hears a tape recording of one of her sessions and when she discovers Chabot’s interest is limited to Melinda, she storms out of the office. When she returns for a final meeting with him, she mentions fourteen additional lives, including her forthcoming birth as Laura and subsequent marriage to the therapist in the year 2038.
