Tri sestry – Three sisters - Ira, Olya and Masha - dream of moving to Moscow from Nizhny Novgorod, relying on the help of their mother, the wealthy owner of a jewelry business, Tatyana. Each has its own calculation: the youngest is going to study in the capital, the middle one is going to move her family, which has "already grown out of this city," and the eldest has a promising career. However, Tatyana has her own plans for life: she returns from vacation with her young lover, who is 15 years younger than her. No more financial support and help with grandchildren, because Tatyana is a woman at the very dawn of her strength and beauty, who has the right to love.
