The Curie Case.

Tony is a studious kid who loves science and dreams of becoming a great scientist one day. His bedroom looks like a laboratory and he has deliberately named his lab mouse after Marie Curie, who developed the theory of radioactivity. Although he is just eight years old, Tony will participate in the National Science Fair with his own experiment. His neighbor Raya, who is also eight, is a student at the School of Dance and is rather naughty and mischievous. She often disturbs Tony and interrupts his concentration and his lab experiments, and she is a friend of Stefan, a bully who is several years older than her. Raya wants to help Stefan pass his math test, but Tony refuses to cooperate, and as a result of that Marie Curie is kidnapped. To get her back, Tony has to face new challenges. The annual ballet production at the school is ruined and fails gloriously, however, a new friendship blossoms.
