The aftermath of a shocking explosion at the Chernobyl nuclear power station made hundreds of people sacrifice their lives to clean up the site of the catastrophe and to successfully prevent an even bigger disaster that could have turned a large part of the European continent into an uninhabitable exclusion zone. This is their story.

Something broke down in Andrey and Nadia's marriage. He goes to live in Moscow, she and the children stay in Irkutsk. On New Year's Eve, the family gets together again, but it seems to be the last time. The word "divorce" sounds quite definite. On January 1, it would seem that everything has already been decided, but a whole chain of events - funny, sad, sometimes even strange and inexplicable - seems to be keeping the family from taking the wrong step. They will all get lost and find each other on this magical night on the island of Olkhon and realize that past grievances are easy to forget, but there is something much more important in life.

In the Russian provinces life seems to have frozen since the 1990s. Here you can hide from the worries of the big world, and heal the wounds of the soul. Thus argues Mila, having decided to return home to the mother’s house after an unsuccessful attempt “to conquer Moscow”. Mila’s sister Galya also wants happiness without thinking about the price. The passion that is aroused in the women by Rustam, a young handsome man from Central Asia, disrupts the family peace. A terrible enlightenment awaits the participants of this family drama.

During the siege of Leningrad a Nazi bombshell destroys the storage of an experimental medicine institute where deadly dangerous viruses were kept. Severe winter weather prevents an epidemic from breaking out in the besieged city. But the spring is coming, and Leningrad is on the brink of bacterial catastrophe. Doctor Maritskaya and NKWD officer Andreew have only three days to save the city.

This is Peter. Not Petersburg, not Leningrad - namely, Peter. A city of big ambitions and opportunities. As a rule, unrealized. Often they joke that there is a particular climate to blame. As if he makes us all a bit lazy and unhurried, and turns the city into an endless northern Magnan. But let's be honest: if the weather was good here, you would have moved here. So thank you, Lord, for the right climate! Peter is first of all people. No museums, no cathedrals or movable bridges. People - this is the present. They fill the city with meaning. Make it alive. Rock musicians and street artists, businessmen and careerists, conductor, cooks, officials, urban madmen, just visiting. Everything is interesting here. Uneasy ... All yours. City swallows.
