Uncle Lesha is an ordinary janitor who works in an orphanage in a small town. At night, he robs the houses of wealthy residents, and he spends the loot on the needs of the same orphanage. His scheme fails when three of the most hooligan pupils accidentally catch Uncle Lesha "at work". The hero has no choice but to take the youth as accomplices… From this moment on, Uncle Lesha's life turns into an attraction, and he has to solve a mountain of problems from his new "companions", confuse the investigation of his own crimes, regain the trust of his beloved woman, pay for serious mistakes of the past, and most importantly, implement his "Robin Hood plan" to the end. The lives of his accomplices are also changing, because thanks to this adventure they acquire a "fatherly figure."

The new year is approaching, and Barvikha’s police department is planning to celebrate it outside the city in the warm company of old friends and colleagues. But unforeseen circumstances in the person of criminals who robbed a large jewelry company, put the holiday at risk. Will the Rublev police be able to return the stolen gems worth millions of dollars and save their holiday before the clock strikes midnight?
