In July 1897, Swedish engineer August Salomon Andrée and his companions Nils Strindberg and Knut Frænkel launched a hydrogen balloon from Svalbard, aiming to become the first to reach the North Pole. Carrier pigeons brought a few hopeful updates, then the expedition went silent for thirty-three years. The film follows what happened next: in 1930, seal hunters on the island of Kvitøya found the men's preserved bodies alongside intact diaries, photographic film rolls, and supplies including morphine and opium. Using those recovered documents and 93 salvaged photographs, along with historians and archival material, the documentary reconstructs the balloon's crash landing on the ice, the brutal trek that followed, and the slow physical collapse the diaries record in unsettling detail. It traces how a venture framed at the time as a triumph of science and national pride turned into a mystery that took over three decades to solve, and lays out what the evidence found on the ice actually shows about how, when, and why the three men died.
