Kenneth Branaugh plays a present-day journalist who ends up caring for a mute amnesiac played by Emma Thompson. They visit an antique dealer who can hypnotize people, and, through hypnosis, she is able to speak. The dealer regresses her into a previous life where she recalls a couple from post WWII L.A. - the man a conductor and the woman a concert pianist. After an argument one night, the woman is murdered with a pair of scissors in her own bed. The conductor is convicted of the crime and executed. Both are reincarnated - but as the opposite gender - and karma intervenes to bring the soulmates together and set the universe right.
Turns out, the hypnotist is the son of the conductor's housekeeper and the pianist's true killer. Emma Thompson's recalled memories lead him to try and kill her again, and he dies when he lands on a pair of scissors Emma Thompson had sculpted.
