Some critics think that Jean Stelli had a gift for thrillers.I don't.His only claim to fame,so to speak ,is a tear jerker called "Le Voile Bleu" which made lots and lots of people cry in the Occupation years.At least,"Le Voile Bleu" had a gifted actress,Gaby Morlay.Here the screenplay is so far-fetched that ,after thirty minutes,the viewer takes no further interest in it.One can ,at a pinch, save two things: -the hero,Didier ,(Gerard Landry),who was traumatized in WW2,gets mad every time he hears a motorcycle or a firework,noises which look like machine guns.-a curious "flashforward" shows Didier on the train,with his sweating brow,remembering the acrobat's fall when the accident is occurring.Word to the wise: take Stelli's "Les Cinq Tulipes Rouges" instead;no masterpiece,but a solid screenplay and a nice documentary side on the Tour De France,sixty years ago.
