Also arrayed against him are Valeria, Malmgrens lover, Captain Romagna, one of the expeditions wouldbe recuers, famed aviator Lundborg, professor Samoilovich, chief of the Soviet rescue mission, his pilot Boris Chukhnovski, and Roald Amundsen who lost his life in the search for survivors of Nobiles expedition.As they try Nobile, the events of the expedition and its failure are depicted. The expedition is successful at first, but ends in disaster. The Italia is weighed down when ice forms on it. Colliding with the ground, the airships gondola is torn from its envelope, the upper frame which contains the airships lifting cells. Freed of the weight of the gondola, the envelope floats away and out of control, taking some of Nobiles crew with it. ........
