Captain Gennady Nevelskoy, an excellent student at the Naval Academy, because of his talent, instead of conquering distant seas, he is forced to teach marine science to the Tsarevich, watching as other people's dreams replace his own. 14-year-old Nadezhda, a young pupil of the Institute of noble maidens, has not managed to find her place in the capital. In her heart, she knows that her real home is lost somewhere in the lands of the Far East, and she needs to return there. Having met each other, Gennady and Nadezhda embark on a great and dangerous adventure — in search of themselves and their place in the world.
