Umberto Nobile has endured years of scorn in Rome for his actions during a disastrous expedition and its aftermath. He imagines a court of inquiry where witnesses and judges are his former crewmen — including Captain Zappi, his navigator, and Finn Malmgren, the meteorologist; also arrayed against him are Valeria, Malmgren's lover, Captain Romagna, one of the expedition's would-be rescuers, famed aviator Einar Lundborg, Professor Samoilovich, the chief of the Soviet rescue mission, his pilot Boris Chukhnovsky, and Roald Amundsen, who died in the search for survivors. As the court of inquiry tries Nobile, the surrounding figures—along with the memories of the voyage—form a chorus of judgment and memory that frames the entire tale.
The narrative then unfolds to depict the expedition itself. The Italia begins with promise, but the voyage ends in catastrophe: ice forms around the airship, the gondola is torn away from its keel, and the envelope that holds the hydrogen cells is freed. With the gondola detached, the remainder of the ship drifts out of control, dragging some crew members into an ever-worsening crisis. Nobile nonetheless keeps a semblance of command over the surviving crew as they endure the harsh arctic pack ice, salvaging what they can and sheltering in a red-dyed tent for visibility and warmth. They manage to repair the radio, but distress calls go unanswered, and a decision is made by three survivors — Captain Zappi, Mariano, and Finn Malmgren — to press across the ice in search of help. Their hopeful trek is a crisp, white odyssey across a landscape that offers little mercy.
Their signals eventually reach the outside world when a Russian radio operator picks up the cries for help, triggering the Soviet rescue mission led by the icebreaker Krassin. The voyage toward salvation is fraught with peril, and Lundborg, the Swedish aviator, finds the group first and lands on the ice. He insists on ferrying only Umberto Nobile, leaving the others behind to contend with the treacherous environment. Nobile agrees, believing he might better assist the rescue from Kings Bay, but the political machinery back home in Rome quickly clamps down on his authority, stripping him of command and ordering him to remain confined to his quarters with no role in the rescue effort.
Desperation pushes Nobile to contact Professor Samoilovich to urge a renewed search for the missing crew. At the same time, Amundsen enters the rescue narrative, only to vanish into the fog of fate as part of the expedition’s tragic arc. In the director’s vision, Amundsen reveals that what looked like hopeful survivors from the air were already dead, and the cold truth of their fate becomes increasingly clear. The party that set out on foot faces brutal obstacles and, in a cruel turn of mercy, must leave Finn Malmgren to die as conditions deteriorate and ice threatens to pull them apart.
Back at the camp, the ice fractures and breaks apart as the survivors cling to hope, ultimately escaping the gondola as it sinks beneath the ice. A distant horizon finally reveals the Krassin bearing down on them, and the crew on deck—Captain Zappi and Mariano among them—wave in a last triumphant sign of rescue. A formal verdict at the court of inquiry is delivered: Samoilovich defends Nobile’s actions by arguing that the rescue of the survivors was a direct result of Nobile’s own daring escape to Kings Bay. Yet the panel’s verdict declares Nobile guilty, a conclusion that Amundsen refuses to accept, deeming the accusers unfit for judgment due to bitterness and moral limitations.
In the quiet aftermath, Amundsen stands as the final witness to the human frailty at the center of the tragedy. He leaves the room, and with him, Nobile finds a measure of peace by acknowledging his humanity and vulnerability. The final exchange unfolds as a meditation on guilt, duty, and what it means to survive: Nobile admits that his choices—some correct, others flawed—were not acts of simple heroism, but human impulses tangled with fear, endurance, and a longing for relief. Amundsen’s late counsel—that frailty is not a sin but a universal human trait—offers Nobile a lifted burden, a quiet reminder that even heroes are only as strong as their capacity to endure their own vulnerability.
