Little Nina & The Piano Thieves [Девочка Нина и похитители пианино]

Eight-year-old Nina is an impulsive and emotional girl, quickly igniting ideas and dropping them halfway. Nina would probably have abandoned her new hobby - music - too, but a strange thing happened: the instrument began to behave defiantly, play by itself and provoke the hostess in every possible way. And soon Nina was completely kidnapped along with him. The villains plan to subjugate the world with the help of the piano.
