The four mountaineers Pierre Allain, Jacques Poincenot, Guy Poulet and René Ferlet climbed the Eiffel Tower in 1947. Forming two ropes, they began the assault on the metal structure of the public monument. The ascent, supposedly illegal by a police officer, turns into a chase... Alain Pol films the climbers going to the end of their sport: they reach the flag pole, abseil down, then cool off in the Seine , while at the end of the scenario the policeman is embarked by the van of the asylum of Charenton which he himself asked for the "madmen of the Eiffel Tower".
