Børge Ousland, one of the world’s greatest polar explorers, is joined by the no less famous South African adventurer Mike Horn for a 1,500 km journey on skis across the polar cap. In addition to the extreme cold and the physical and psychological challenges caused by the darkness, there are the almost daily dangers of this ice that is getting so thin that it requires enormous risks to maintain their progress.

Seb embarks on a unique journey by joining Mike Horn for a few days on a stage of Mike's new expedition. Unaware of what to expect, Seb returns with lots of beautiful memories and lessons. Although not presented as a traditional documentary, Seb encapsulates his experience in a captivating vignette, eager to share this remarkable chapter of his life with others.

One spring day, Mike Horn left his beloved wife and two daughters on a shore to circumnavigate the globe alone, following the equator. On foot, by dugout canoe, by sailboat, or by bicycle, across three oceans and two continents, Mike Horn journeyed along this invisible thread, never straying more than forty kilometers from it. Here, he recounts how a solitary man manages to blend into nature, choosing whether or not it will let him pass. In the Brazilian rainforest, bitten by a snake, he remained blind for four days, semi-conscious. But the greatest danger is humanity and its wars. In Africa, rebels arrested Mike Horn and sentenced him to death. He escaped by the skin of his teeth. Why all this? Because he wanted to fulfill his dream, to delve deeper into the encounter between nature and humanity. In this extraordinary story, we discover a man who is afraid, who marvels, who is in pain, but who moves forward, always.

Mike Horn has gone along the Arctic Circle alone for 27 months, 20,000 km, without any motorized transportation. He has faced ice storms, temperatures from -70°C to 15°C, polar bears, a fire that destroyed most of his equipment and nearly burned him alive and he was the first man to cross entire Siberia on foot. But first of all, Arktos is a human tale. He meets an Inuit who teaches him to build an igloo in 20 minutes; Vassia, an elderly Russian fisher; among many others. After all, Mike met himself.

Adventurer Mike Horn and his friends travel through 13 countries in an attempt to get on top of the most difficult mountain in the world. Immersing into different cultures and breathtaking landscapes, they get closer to climbing K2.

In July 2024, Liv Sansoz and Bertrand Roche (aka Zébulon) made history in Himalayan mountaineering by climbing K2 (8,611m) without supplemental oxygen, then paragliding from the summit. The couple achieved a highly coveted first, and for Zébulon, the feat was all the more impressive as he had already completed the first tandem paragliding flight from Everest in 2001. More than just a climb, this film is a love story where Liv and Zeb share their doubts, emotions, and determination, carrying a shared dream where every step is taken together, united to the very end.
