Nastya Sablina is turning sixteen, and, filled with emotion, she begins to reflect on "the most important day of her life."

Meet Nastya, 29 years old, designer-architect, married. Five completely different inner selves get along in it. This is the inner child; the hostess responsible for the attacks of all general cleaning; the control-obsessed demanding parent; the goddess of pleasure and a self-confident, daring careerist. Each of them has their own interests and ideas about happiness. They cheat, argue and fight among themselves. But when Nastya simultaneously loses her job, husband and best friend, the five will face a difficult task. They will have to learn how to negotiate with each other and make compromises — all in order for Nastya to be able to say with confidence: "I love myself all!"
