The only means to reach Zimmer is through his beloved mistress Chiara, who is under surveillance of the police and the mobsters. While traveling by train to the country nearby Nice, the common man François Taillandier, who has the same body shape of Zimmer, is select by Chiara as if he were Zimmer and used as a bait to lure those that are pursuing her.
