From childhood, Sanya Grigoriev knew how to achieve success in any business. He grew up to be a courageous and brave man. The dream of finding the remains of Captain Tatarinov’s expedition brought him into the ranks of polar explorers. The life of Captain Grigoriev is full of heroic events: he flew over the Arctic, fought against the Nazis. He faced dangers and had to endure temporary defeats, but the persistent and purposeful character of the hero helps him keep the oath he made to himself in childhood: “Fight and seek, find and do not give up.”
