But it's not that simple. No one wants to help them. Getting information is difficult. Dima's charm comes into play. He finds out at the passport office that Lyudmila Petrovna is still registered in her apartment. Sveta visits nursing homes, but Mama isn't there. Shurik recruits homeless people, trying to find out through them where Mama is. They learn that half the apartments in Mama's building belong to some investment company. And there are no families or elderly people left in the building for a long time. Except for one grandfather, Andrei Petrovich, who greets all guests with a gun.
