On the eve of 1900, the son of a poor lamplighter, 18-year-old Matvey, loses his job due to an annoying delay. But he finds a real friend. His new acquaintance Alex skates like a god, but not just like that: he is the leader of a gang of elusive pickpockets who clean the pockets of Petersburgers and guests of the capital on the city’s canals. They take Matthew into their ranks and teach the intricacies of the craft, as well as cunning speed skating tricks. At the same time, the beautiful noble girl Alice languishes in the palace of her father, a major dignitary. She has an admirer: a young and ambitious prince. But chance – or fate itself! – brings Alice and Matvey … This meeting will change their lives forever.
