First film in a series of three with Over-Ice and Oversand and one of the first films on free climbing shot in the cliffs of the Gorges du Verdon in several parishes. We meet a certain Patrick Edlinger, Patrick Bérhault, but also Jean-Marc Troussier, Jacques Perrier, Stéphane Troussier, Hugues Jaillet, Gilbert Thomann, Odette Schoënleb, Bernard Gorgeon, Christian Guyomar. Thanks to the program Les Carnets de l'aventure, then broadcast on Antenne 2, and its producer Pierre-François Degeorges, this film was made. The chain gave its production agreement during the day, while the climbing was very confidential, no one knew Patrick Edlinger and the project itself contained only a few lines on a sheet
