Leaps and Bounds (2007)

Azad comes to Sweden by mistake. In order to blend in with the family that hides him, he must pretend that he is nine years old. Suddenly he's quite alone in a new country and doesn't understand the language. But with the help of a spaced-out hot-dog vendor, the coolest guy in school, and world champion Kajsa Bergqvist, maybe he can find his real family again.
