Maurice and Katia Krafft: To the rhythm of the Earth

Close and daily, sometimes comical but often tragic, sleepiness takes an important place in our lives. Suddenly falling asleep, sometimes with their eyes still open, affects more than 10% of the population. The leading cause of fatal accidents on motorways, drowsiness is also prevalent in the world of work. A silent, irrepressible phenomenon... a flaw in a system of performance, speed, reactivity. So what is happening in our brain? Can we control the conditions of sleepiness? By working on sleep and especially on the functioning of wakefulness, researchers are trying to understand the biological and environmental mechanisms that keep humans at the peak of their abilities. After a clear technological improvement, it turns out that man, having become an expert and process controller, finds it very difficult to focus his attention over time.

The Algerian Sahara is the most exceptional deserts. He densifies everything he hosts, men and nature, and invites you to pay attention to the world. Jean-Louis and Odette Bernezat were born at the foot of the Alps, but it was in the Sahara that they found their way, and devoted almost forty years to the discovery of this environment and have extraordinary knowledge to share. Director Maryse Bergonzat accompanies them, in a meha, in the Hoggar in Algeria, with their Tuareg friends. A privileged place to appreciate the desert, its landscapes, its inhabitants, its laws and its stories, in the company of exceptional guides.

The two brothers Jean and Pierre Ravier have opened almost all the "classic" (difficult) routes in climbing and mountaineering in the Pyrenees. Roped together at the waist using a few flat knots and little equipment, the two twin brothers achieved more than 200 firsts across the entire massif. A unique style and commitment, a state of mind made up of adventure, literature, inventiveness and friendship. Unclassifiable and outgoing, after 60 years of Pyrenees, their desire for the mountains is intact. When does a race start? How does the idea, the desire, come about? What sense does it make to only achieve firsts? And what is the role of the Pyrenees themselves in this reciprocal and endless game of attraction?
