The end of the 17th century. Patriarchal Muscovy is mired in boyar conspiracies and Streltsy rebellions. Tsarevna Sophia – the daughter of Tsar Alexei Mikhailovich Romanov and his first wife Maria Miloslavskaya – is doing everything in her power to remove the young Peter from power. Together with his mother, he goes to Preobrazhenskoye, where he first displays his strong character and inquisitive mind. The future emperor forms his toy troops and masters military affairs. At this time, he grows close to his orderly Aleksashka Menshikov, who will later become the emperor’s favorite. But it is not only learning and military affairs that stir Peter. In the German Quarter, he meets and instantly falls in love with a simple girl named Anna Mons.
