The blueprints of an aeroplane built from an ultra-secret metal are stolen from national security. French secret service agent Walder believes that the documents are now in Switzerland, in the hands of a man named Lindbaum. The latter agrees to hand over the blueprints in return for a large sum of money. Another agent, Francis Coplan, is sent to Switzerland to handle the deal, but Lindbaum only has half of the documents because he was double-crossed by Kalpannen, an international crook. With the help of Heidi, a Swiss correspondent, Coplan sets out to identify the members of Kalpannen’s gang, only to find that they have all been murdered…

1984 film by André Génovès

1955 film by Pierre Foucaud

The film is at first a documentary about the early days of French television. The various techniques of the new medium are explained through the filming of a flamenco show. The second part is an exercise in futurology. Basing himself on René Barjavel's revolutionary ideas, Raymond-Millet imagines all the ways television might be used in the days to come. His finds foreshadow the videophone, the cell phone, the Internet, electronic surveillance as well as virtual images. The whole thing is presented in a humorous unpretentious way.
