no Megacine. Guido Magnone's incredible adventure begins strangely on the banks of the Ourcq canal among a group of kids who dream of swimming. Guido, the solitary son of "rital", dives to get noticed, succeeds, takes a liking to it, breaks his first record, collects medals. At the same time, he draws, attends the Beaux-Arts, is accepted with open arms and befriends the sculptors César and Féraud. At the end of the war, during a health stay in Chamonix, it is love at first sight for the mountains, climbing. Guido's ascent is now dizzying. He stormed the west face of the Drus, then the Fitzroy and the Tour de Mustagh, summits reputed to be impossible. He rubs shoulders with the greatest, Lionel Terray, Maurice Herzog, and participates in the Makalu expedition, camera in hand, or those of Jannu and Chacraraju. Later, in his fifties, Guido hangs up the carabiners and participates in the foundation of the UCPA
