In 1979 Reinhold Messner thought of an ideal route to climb K2 along the south-south west face, the "Magic Line". This route was attempted by a French expedition in 1979 without success. A Polish expedition instead, with Wroz, Piasecki and Bozik, succeeded in the attempt but Wroz did not return. The bodies of Renato Casarotto, Lashr Khan, Hogn Smlich and Allan Pannington also lie at a height of 7000 m. Despite this, in July 1988, a Yuogslavian expedition attempted the climb and made this film, along the most difficult route leading to the summit of K2.
