Russia, 1744. Empress Elizabeth is childless and increasingly ill. Her nephew, Tsarevich Petr Fedorovich, the son of Anna, Elizabeth's elder sister, is appointed as heir. This is a quarrelsome, foolish young man who from an early age became familiar with alcohol and tobacco. In order to strengthen the dynasty, Elizabeth decides to arrange the marriage of her good for nothing nephew, offering him one of the German princesses as a bride, Sophie Friederike Auguste, who by virtue of her young age is affectionately called "Fiquet".

Vice-chancellor Bestuzhev summons Aleksei Korsak and Alexander Belov and gives them an important assignment. Friends should hand over a personal letter to Prince Anhalt-Zerbst, and then deliver "Fiquet" and her mother incognito to St. Petersburg. On the way to their homeland, their third friend, Nikita Olenev, unexpectedly joins them, who at that time was studying in Germany. True friends Gardes-Marines are together again, and they are bringing a precious cargo with them to the distant snow-covered Russia: the future wife of the heir to the throne and her mother.

But such political action can not go unnoticed in Europe. French diplomacy starts another intrigue, and Chevalier de Brillieu again is its tool. Using his skill of a clever Don Juan, de Brillieu should become the lover and confidant of Fiquet's mother - the duchess Johanna, a lustful and extravagant woman, up to her neck in debt. Then acting through the duchess, France will be able to influence the heir and his wife in its own interests. De Brillieu takes up the work with ardor because personal animosity is involved. After all it was the Gardes-Marines who stole Anastasia Yaguzhinskaya away from him, a Russian beauty whom the Frenchman still loves. And now de Brillieu prepares a trap, which must include friends and Gardes-Marines, and "Fiquet" with her mother...
