Gombessa Expedition 4 Laurent Ballesta went to observe a gathering of thousands of groupers during the full moon of June 2014 (Le mystère mérou) in the southern pass of the Polynesian atoll of Fakarava, where he discovered a pack of over seven hundred grey sharks. How can this unprecedented density be explained? Could it be that social behaviors govern this wild horde? During three years of preparation, he and the other divers on his international scientific team tamed their fear by abandoning the defensive reflexes that provoke shark aggression, with the aim of slipping into the heart of the raging pack to study and film it from the inside. Sharks fitted with microchips, receiving antennas, hydrophones, an ark of 32 synchronized cameras...: a whole technological arsenal is mobilized for the project. As the groupers approach for their annual spawning, what battle plan will the sharks deploy?

The fascinating landscape formations of Iceland in the North Atlantic bear witness to the beauty and primal power of nature. They were created through the interaction of powerful volcanic, geological and biological processes that have been changing the face of the earth for billions of years. This is what the Earth might have looked like four billion years ago. Iceland is the realm of ice and fire. Nowhere else is there such a high density of volcanoes. The landscapes, which are continually reshaped by eruptions, make the island a natural laboratory full of clues about the formation and development of the earth. The documentary follows a group of scientists through the most active areas of Iceland, along a mountain range that has emerged from the ocean. On the slopes of the volcanoes, in the fog of the fumaroles and on streams and rivers, the three researchers explore how the first forms of life populated the earth's surface and in what evolutionary steps they took over the earth.

On July 5, 1816, the raft of La Méduse, about 20 by 12 meters, began its slow drift. They left at 151 and 13 days later, after a hellish journey, arrived at 15... Who knows the true story of Le Radeau de La Méduse? Painted in 1819, Théodore Géricault's romantic masterpiece became so famous that it has since overshadowed the true story that inspired it. In June 1816, during the Restoration under Louix XVIII, a French ship, the Méduse, left the port of Rochefort bound for Senegal. Its crew, made up of the new governor Schamaltz, company officials, troops and the expeditionary corps, had to settle in this former colony restored to France by England. In all, some 400 passengers. But due to the unpredictable cartography of the time and the short-sightedness of its commander, La Méduse ran aground on a sandbank off the coast of Mauritania.
