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.

This made-for-TV documentary introduces the layperson to concepts and technologies that were emerging in computer interface design in the late 1980s and early 1990s: hypertext, multimedia, virtual assistants, interactive video, 3D animation, and virtual reality.

Immortality and eternal life: Will this great human dream come true? In any case, cryonics is making ever greater progress, human cloning no longer seems impossible and research is being carried out into the digital reproduction of the brain. Taking stock in the USA, Canada, Europe and Russia. The documentary delves into a world in which all-too-human people refuse to simply be wiped out by death. It shows how difficult it is to resist the promises of eternal life and also highlights the economic interests behind such endeavors.

The Mediterranean. Because people have been travelling there for thousands of years, it is believed to be without secrets. And yet, far below its surface, lie vast unexplored territories, luxurious gardens worthy of the finest tropical coral reefs. These natural wonders are inaccessible to the traditional diver, in a twilight zone, between 60 and 120 m, where there’s less than 1% of sunlight. If diving at such depths is always a challenge, staying there is a fantasy, a utopia that becomes reality in Planet Mediterranean. In the tradition of Commander Cousteau and his "houses under the sea," the team of diver-photographer Laurent Ballesta is undertaking a new world-record setting mission in complete freedom and without time limit.

The "gravity" nightmare is becoming a reality: tons of rocket and satellite parts have been scattered into space over the past 60 years. The fragments collide with other objects, producing more and more scrap - a proliferation that has long since gotten out of control and poses an acute danger to rocket launches and space stations.

July 20, 1969. Apollo 11 lands on the surface of the Moon. Such a feat was apparently performed to the greater glory of all mankind, but actually it marked the end of the space race disputed by the two great superpowers of the time in their eagerness to arrive before and the beginning of the spread of the Cold War into space. Nowadays, the struggle continues, but the main competitors and their purposes are others.
