The French freediver Stéphane Tourreau is vice world champion in constant weight apnea, a demanding discipline that consists of diving as deep as possible using only his own muscle strength. His passion: to explore the most beautiful diving spots on the planet.

Always looking for unique and introspective sensations, Stéphane Tourreau decided to explore the island of Mayotte, jewel of the Indian Ocean. In this diver's paradise, he has set himself a major sporting challenge: exploring, without a tank, at a depth of 70m, one of the volcanic island’s most prestigious underwater sites. An opportunity to discover this archipelago from a very different angle.
