Based on a true story. Two fighters of 'Donbas' Volunteer Battalion get locked inside city of Ilovaysk after regular Russian army enters Ukraine and shells the surrounded divisions of Ukrainian Army in the infamous would-be 'green corridor'. The fighters survive thanks to the help of the locals and manage to break out through the front line to reach the freed territory. Taras Kostanchuk who is playing himself as 'Beshoot' is that same Donbas commander who is the prototype of the story. Half of the actors and extras are real 'Donbas' volunteers who survived the battle.

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.
