The film documents a Slovakian expedition crossing the North Pole glaciers reached after a long, difficult and dramatic march with sledges drawn by dogs. The expedition crosses the islands of Greenland on the outward journey and returns by the way of the Canadian archipelago which is no less difficult and dangerous. It is impossible to distinguish between the glaciers, water and land which causes serious psychological, as well as physical, fatigue. The scenes not only stress the geographical, morphological and zoological features of the Arctic regions, but especially the human element: the difficult test the conquerors of the Pole face with determination, the accidents on the way, the adaptation to the eternal twilight, the struggle with the elements and the extreme physical effort.
