The Grand Canyon is a breathtaking natural monument. It's one of the planet’s best-known landscapes, yet we often forget that it tells two billion years of the Earth's history. Geologists Karl Karlström and Laurie Crossey are the leading experts on this. Over the course of 8 days, they descend the Colorado river and tackle hundreds of rapids to unveil the mysteries held in the Grand Canyon, and the place that humans occupy within it.

The return of numerous displaced wild animal species to Europe has been observed since the 1950s. Now scientists have decided to accelerate this development even further. The aim: to create new wild regions. The method: "rewilding", which is essentially based on reintroducing large animals such as bison or bears to Europe.

Dive into a world of ice and freezing waters to discover a little-known yet iconic marine mammal, the Beluga. Today, this fascinating white Whale that lives in Arctic and sub-Arctic waters is once again in decline, especially in the St. Lawrence River. Is it due to the loss of sea ice? The growth of ocean shipping? Noise? Contamination? Genetics? Alongside world-renowned researchers, this documentary in 4K takes us on a major scientific quest that sheds new light on Beluga populations which are fighting for their survival. Over four seasons, we share the daily life of an international group of scientists who study this extraordinary species in its native habitat to better comprehend their existence and understand why they are endangered.
