In the summer of 1897, a giant balloon named Eagle left Sweden with three explorers and began their expedition to the Arctic. The expedition team was led by Andrey, a middle-aged engineer who was brave and stubborn, determined to explore the secrets of the polar regions, and his companions were two young explorers: Frankel and Stirindberg. The balloon landed on the glacier after three and a half hours of sailing, and the three brave men fought a life-and-death struggle in the face of the dangers of nature. 33 years later, their frozen bodies were found on a small island. Was Andre's adventure meaningless or great? Did Andre know he was going to die like this? This is still a mystery for future generations. However, the flight of the Eagle will go down in history as a human conquest of the polar regions.
