A documentary about André Payraud's descent of the Mont Blanc torrent by swimming down it. "I've always had a thirst for adventure. At 19, I was in a diving club and I loved Jacques Martin's show, 'Incroyable mais vrai' (Incredible but True). I dreamed of participating in this hit program." After careful consideration, André Payraud had the idea of ​​the century, an idea that would attract media attention: to descend the Grands-Montets glacier on his stomach, wearing a full wetsuit (mask, snorkel, fins, and neoprene suit). A crazy idea that drew a flood of press coverage. The film, "Swimming Down the Mont Blanc Torrent," directed by Didier Lafond, was broadcast twice on France 2 and even won an award.
