100 years ago, the Russian Empire ... Christmas Eve. December plugs, holiday celebrations, balls and modest luxury holidays, titled nobles and ordinary peasants, the royal family and the soldiers of the First World War, progressive poets and the first skaters - everything was different, except ... the holiday. People prepared, lived, believed dreaming and waiting for this miracle - Christmas!

Anatoli Novoseltsev works in a ratings company, whose director is an unattractive and bossy woman. An old friend of his, Yuri Samokhvalov, who gets appointed assistant director, wants to make Novoseltsev the manager but encounters objections from Ludmila Kalugina, the director. Samokhvalov then advises Novoseltsev to lightly hit on the boss. Ironically, Novoseltsev and Kalugina fall in love with each other.
