Alyosha will be torn between the football field and the school desk, and the family will have to learn to live in a constant multitasking mode. Meanwhile, Misha and Lila will have to move to a residential area, where a quiet life is quickly giving way to the need to earn two apartments at once — a rented and a mortgage. It's time for Gena and Zubova to enter a new stage of their relationship — at least, that's what Margarita Alekseevna thinks. At the same time, Eva is facing business competitors, the concierge Nurik continues to surprise with his antics, and the office routine of Meridian remains as boring as before.

Sasha, Tanya, and their entire large team of friends and relatives return to face domestic disasters, strange neighbors, office misunderstandings, and—unexpectedly — a new character who won't let them home. Sasha will try to be the mainstay of the family, Tanya will try to combine maternity leave with work and the struggle for a nanny, Katya will try to build a personal life after being fired, and Zubova and Gena will try not to go crazy with each other.
