Planetarium
In the late 1930s, two American sisters, Laura and Kate Barlow, travel to France where they perform séances at cabarets with Laura hosting the session and Kate channeling the spirits. A public performance of theirs is seen by French film producer Andre Korben. Impressed by their act, he books them for a private session and is moved by the spirit that visits him.
