Franck is an astrophysicist. His job is to perform laser drillings with the Lynx, an exploration rover on Mars. Assisted by his collegues, he spends the night looking for traces of organic life by examining rocks. In the morning, he will meet with his son who has been traveling around the world after staying with his mother.

From America, England, France, Italy and Japan. From each corner of the earth, five climbers – Sam Elias, James Pearson, Caroline Ciavaldini, Jacopo Larcher and Yuji Hirayama – attempt to open a new multi-pitch route on the basalt island of Reunion. Lost in the South Indian Ocean, Reunion is the childhood home of Caroline and, after traveling the world for several years as a professional climber, returning was something she had to do. By working together as climbers and friends, the team is able to open, ground-up, one of the hardest multi-pitch rock climbs in the world.

A garden in Réunion

160 km southwest of Reunion Island, just a few dozen metres beneath the surface of the Indian Ocean, lies the peak of an underwater volcanic structure known as Mont La Pérouse. The base of this enigmatic geological formation lies 5000 meters below sea level, with a size comparable to that of Mont Blanc. Permanent currents and strong winds characterise this site in the open seas, culminating in complex diving conditions under which Laurent Ballesta, together with his Gombessa diving team and local researchers had to navigate in order to conduct the study in depth. Further techniques such as observation and photographic inventory, biological and geological sampling, and the use of cameras and sonars were employed in this challenging expedition.
