A near future where people can travel through time-though only a select few. Lavrik, a charming con man and gigolo, has been exposed and left without a source of income. The only way for the hero to improve his situation is to fulfill a task assigned by the billionaire Boltzmann and travel back in time to retrieve the Hymen Cup. Lavrik is transported to Moscow in 1913 and begins hunting for an artifact located in the Bridal Cashier's Office, a bank where dowries are accumulated. But Varya, a principled woman who is also a member of the Cashier's Office and has a keen sense of deception, seeks to ruin Lavrik's plans. Lavrik devises a plan to outwit Varya and, with her help, pull off the scam.
