An exciting modern epic of scientific and human achievement: four years spent crisscrossing the oceans to study and document life between the surface and 174 m (571 ft) down, scientific breakthroughs on natural fluorescence and deep-sea corals, and the invention of Capsule, a lightweight, self-sufficient underwater habitat, inspired by Jules Verne, that makes it possible to observe and study the seabed with no time limits.
Between Two Worlds tells the story of this team led by Ghislain and Emmanuelle Périé-Bardout, accompanied by their two children Robin and Tom, with its difficulties and riches and their increasingly strong desire to devote their missions to scientific research, education and awareness-raising, in the service of a better understanding and preservation of the oceans.
