During the filming of Frozen Planet, the team got unprecedented access to film the story of the South Pole Station - the most extreme and remote scientific research base on earth. This film traces the history of the base, which began unwittingly with early explorers like Scott and Amundsen and their quest to be the first humans to reach the South Pole, dragging tools and supplies behind them. Today, modern scientists have access to much more hi-tech instruments and we meet a team working on one of the most extreme scientific projects on earth.
