Thomas Dulac

Roger Frison-Roche born in Paris in 1906 and moved to Chamonix at the age of 17. He was quickly adopted by local mountaineers and became the first guide in the Company not to have been born in the valley. He is also an insatiable explorer, in love with landscapes and peoples, having traveled from the Hoggar to the Sami camps in Lapland. And the author, among others, of the famous adventure novel Premier de Cordée! This documentary, made up of archive images and interviews, exposes the prolific life of a man who communicated his passion for the mountains by all possible means. A young journalist from Chamonix follows in the footsteps of Roger Frison-Roche. She meets people who knew him and others who followed in his footsteps: guides, filmmaker and author Philippe Claudel, a director, his family; on a trip to Lapland, Algeria, Chamonix.

In the heart of the Hoggar Mountains, Algerian and French climbers meet on the legendary walls of the central Sahara. More than just an ascent, Tissalatine tells the story of an encounter with oneself, with the land, and with history. The film also retraces Thomas Dulac's return, ten years later, to a site he helped to open up. Driven by the profound voice of singer Djam and the vision of director Hamza Mendil, Tissalatine unveils a living, vibrant Sahara, far removed from clichés, in a sweeping epic of adventure, brotherhood, and spiritual elevation.
