Christmas is coming. In a letter to Santa Claus, Ania writes that she would like to get a brother, but she only gets a doll. Then she is offended and cannot believe that no one believes in Santa Claus. Ania goes to meet Krzyś, the boy from the neighborhood. It turns out that he has never been visited by Santa Claus, so Ania dresses up as Santa Claus and gives him 3 gifts. Meanwhile, Krzyś is already 4 years old, so he should get 4 gifts.
