The parents get divorced and Jo has to move to a new place. One day, Nordstjerna goes out, and Jo discovers that a girl with magical powers lives in the attic.

A magic stone turns 9-year-old star child Elly into the guiding North Star. But she hates that she can never leave her home because of it - and she runs away. On Earth, 10-year-old Jo has to move because his parents split up - and he doesn't feel at home anymore. When Jo and Elly meet, they both feel out of place. But they help each other learn that not everything is about them, and just in time for Christmas they save the world together. Everyone can become a guiding star; because, in the end, aren't we all made of stardust?—themoviedb
