Antarctica, a legacy mission 

While emptying her grandparents' house, director Jeanne Lefevre discovers the journal kept by her grandfather during a scientific mission to Adélie Land, French Antarctic Territory, in 1960. Atomic engineer Bruno Parlier had never spoken of this trip to his family. With her archives in hand, Jeanne decides to follow in his footsteps, to Antarctica.

To reach Antarctica, one must cross the most dangerous seas on the planet. The Roaring Forties, the Furious Fifties, the Breaking Sixties, then the "pack," the perilous sea of ice that heralds the arrival of the ice floes, and the "ice barriers," those immense frozen maritime expanses that extend the terrestrial glaciers of Antarctica. A less perilous task today than Bruno Parlier described it in December 1959.

Life at the Dumont d'Urville base runs like clockwork, with chores divided among the residents. Jeanne discovers passionate personalities, thirsty for adventure and eager to change things through science. Through them, she paints a portrait of her grandfather.

Since the first Antarctic mission in 1957, the same beliefs have drawn these individuals to this inhospitable continent. But since then, the stakes have changed.

In a land that words cannot describe, marked by the legends of the first explorers and pioneers and where everyone wants to leave a mark, Jeanne now has the mission of sharing the life and work of those who are there with as many people as possible.
