One day, little Olya told Father Frost that she wants to grow up as a beauty and become a famous actress. Her wish came true, but somehow it didn’t bring the girl happiness. Meanwhile, Olya’s twin sister, Tanya—a regular French teacher—is also unhappy in her ordinary, gray life that she feels is so drab.
And then Olga suddenly decides to swap fates with Tanya for exactly one month—just until New Year’s. Said and done! That’s when surprises started raining down on the sisters—like gifts from a sack of Father Frost.
