The film deals with the first no-aid crossing expedition of the ice cap in the Southern Patagonia of Chile. Børge Ousland and Thomas Ulrich left the village of Tortel on 24th August 2003. They planned to cross the largest ice cap in the world from one country to another with no external support. After three days in the Patagonia fjords on board their kayak they got to the foot of the glacier Jorge Montt, where they turned their kayaks into sledges that could be towed on their skis. The weather was unbelievably harsh, with strong wind and ice storms. The territory was not accurately mapped and therefore they had to use the satellite images received on their GPS. The two men had taken this journey in winter, when the weather was slightly milder, although dark and cold.
