The fanciful tale of an introverted little girl who grows up believing she has the power to make wishes come true. She must reconcile this belief with reality when, as a young woman, she journeys to Moscow and grapples with love, modernity and materialism.

One day in the life of the courier girl

Twelve-year-old Anya discovers a mysterious stranger in her secret hideout after another quarrel with her mother. A stranger who has settled in an abandoned house next door reveals to the girl a fantastic world that was hidden in the routine of summer cottage life. However, not everyone is ready to understand her friendship with an adult man, who obviously has something to hide. Anya is also shocked and disappointed when it turns out that she is not the only one — the mysterious stranger also communicates with her friend Amaranta, also gives her gifts and tells stories. They are angry at him and at each other. The stranger is both their main secret and a bone of contention.
