Panel Khrushchevs are destroyed. The excavator crushes concrete blocks like cardboard. It looks a bit like a dragon with a long neck. And he almost destroyed the house next to the one in which Sasha and Lena live. They still live, although the rest of the tenants have already moved out to new apartments, and utilities have long been turned off. When the dragon gets to the home of Sasha and Lena, it will be too late for them to look for a new one. So they need to do something now.
