A childhood vow to find a lost Arctic expedition? That's some serious homework.
From childhood, Sanya Grigoryev was able to achieve success in any business. He grew up a courageous and brave man. The dream of finding the remnants of Captain Tatarinov’s expedition led him to the ranks of polar explorers. The life of Captain Grigoryev is full of heroic events: he flew over the Arctic, fought against the Nazis. He was in danger, had to endure temporary defeats, but the hero’s persistent and purposeful character helps him to keep his vow made to himself in childhood: “Fight and seek, find and not give up.”

Trivia, insights & behind the scenes
The novel was mandatory Soviet school reading for decades; this adaptation helped cement Kaverin's status as a national literary treasure.
The adult Sanya and childhood Sanya never share scenes because the actors—unrelated—looked nothing alike. Soviet casting: an art, not a science.
