The film will tell the story of an old summer cottage village, the residents of which have been friends with their families for several generations in a row. Together they meet new summer cottage seasons, celebrate holidays, cope with troubles and failures.

Nika Mstislavova, the heiress of one of the oldest summer residents, who died under rather strange circumstances, settles in the house of her late grandmother and sets herself the goal of finding out the true nature of the mysterious and terrible events taking place in the village...

Nika is immediately overwhelmed by a mass of impressions, new and already forgotten, because the girl grew up in these places, here she was raised by her grandmother after the sudden death of her parents. Many of the faces she meets on the street seem almost family, although these people have changed a lot and aged since Nika left for Moscow. Familiar and unfamiliar summer residents make up a narrow circle of old-timers, many of whom remember and love Nika's grandmother, Veronika Vitoldova, but no one wants to even admit that a real crime could happen in their quiet and cozy little world.

However, Nika does not have to fight for her rights alone. Her common-law husband, the famous Moscow writer Pavlov, and the young architect Vetlitsky, who is building luxurious houses for representatives of the prosperous new elite in the village, are always by her side. They quickly realize that the roots of the crimes go back to the village's past sixty years ago...
