In the fall of 1920, when the Red Army fought on the outskirts of Novorossiysk, one of the best ships of the Russian fleet “Oryol” stood at the berths of the port. The ship's boatswain, the hiding communist Mikhail Gruzdev, convinced Captain Chistyakov to keep the Eagle and return it to the red flag. Soon the legendary ship aboard the White Guards pursued by the Red Army left Novorossiysk. History left no trace of the further fate of the "Eagle" and its crew. It was believed that Chistyakov handed over the ship to the White Guards, and they took him abroad. Many years later, the captain of the ship “Flounder” Mikhail Gruzdev, confident in Chistyakov’s uncompromising attitude, obtained permission - and set about searching for the missing ship.
