In 1909, Denmark's "Alabama Expedition" led by captain Ejnar Mikkelsen embarked on an arduous journey aimed at defending the state's territorial claims.Their goal of this trip was to refute the United States' claim of sovereignty over northeastern Greenland - a claim based on an unproven assumption that Greenland is not a complete piece of land, but is composed of two separate lands. In this expedition that concerns national reputation and belief, Mikelson decided to personally lead the team member Iver Iversen, who is still experienced, to ride a sled across the boundless ice field, leaving the crew members on the boat waiting for news.The two of them went alone into the extremely cold land, facing the unknown and danger, which was both a test of courage and a trial of will.Every step of theirs carries the country's expectations and scientific spirit of truth-seeking. On the snow-covered earth, there is a legend about faith, friendship and sacrifice.
