There are conflicting reports as to the true inspiration for the film, lawyer Jules François Clermont or actor Claude Dauphin. Some sources claim the film is based on the real-life activities of Jules François Clermont, who wrote and starred in the film under the name "Paul Clarus". In September 2011, The Daily Telegraph published an article noting that writer and actor Claude Dauphin had collaborated with Hitchcock to recount his own experiences of operating an underground radio station in Nazi occupied France.
Paul Clarus, a French actor (played by "Paul Clarus") is chatting with his fellow actors (the "Molière Players") as they put on their makeup before a performance. He reminisces about a very unpleasant Vichy official, the Chef de la Sûreté, (Paul Bonifas) that he knew when he was part of the Resistance on the island of Madagascar during the Second World War. The events on Madagascar are shown in flashback.
Paul Clarus pretended to be loyal to the Vichy official, while he simultaneously worked as the head of the Resistance movement. He ran an illegal pro-Resistance radio station "Madagascar Libre", and helped arrange numerous boats to take loyal Frenchmen out of the island to safety. Finally when the Vichy government falls, we see that the Vichy official is nothing but a turncoat; in his office he rapidly replaces a portrait of Marshal Philippe Pétain with a portrait of Queen Victoria, and he changes his bottle of Vichy water for bottles of Scotch and soda water.
