A musical retro drama. The story of the heroes of the film "Everyone is Dancing!" is inspired by the poetry of Leningrad lyricists of the 50s and 60s and partly by the motives of Fazil Iskander's story "Retribution". The film tells about the Ligovka district of St. Petersburg, known to every resident of St. Petersburg as a place where punks live.

A unique ring has been stolen from the Hermitage! A rare artifact that has been passed down from generation to generation of the imperial dynasty has disappeared! A detective agency, 'Michelle,' has taken on the search. However, they face unprecedented pressure. It is at this point that a true journalism ace, paparazzo Yegor Leonov, gets involved in the investigation. For him, this is a way to earn money, as it is already known that General Burlyaev, criminal authority Vasily, and monarchist Prince Sokolov are involved in the theft! The main task for Yegor and the staff of the 'Michelle' agency is not just to find and return the ring to the Hermitage, but to do so discreetly. After all, the loss of such a rarity could cause an international scandal!
