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.
