The film takes place in Chernihiv in the first days of the full-scale Russian invasion of Ukraine. A group of people of different ages and social status find themselves in the basement of a high-rise building, where they are hiding from shelling. After the explosion, the entrance is blocked and everyone stays in the basement for 7 days, facing hunger and constant danger. Under the pressure of fear and uncertainty of who will find them — the Ukrainian army or the Russians — people are divided into warring groups.
