It's a big milestone in the Bogdanov family - twin brothers Egor and Denis are turning 30 years old. Their mother Olga is trying to gather the whole family at one table, but neither her ex-husband Aleksandr nor the children are in the mood for a holiday. Aleksandr is preoccupied with his new relationship. Son Denis, in addition to difficulties with his wife, faces a scandalous dismissal. The youngest daughter Musya, secretly from her parents, agreed to surrogacy in order to earn money for a startup. And only the eldest Karina is trying to preserve the family tradition of getting together. And she succeeds: three generations come to the holiday. Only the chair of his twin brother Egor is empty. It's been 13 years since he died and the family fell apart.
