Karl did not want to relocate to Copenhagen. Mom got a job in the capital and must go there! Because if anyone ever takes into account what he thinks and feels the 12-year-old boy? Karl worst suspicions come true - Copenhagen turns out loud and ugly.
Paradoxically, in his new class - full of children from different parts of the world - Karl becomes the object of ridicule. Run away to my grandparents, as planned, if not for a meeting with Sawsan. Outspoken Muslim teaching him how to speak well 'kopenhasku'. And also can sing.
One of her songs was elected to the Danish version of the Eurovision Song Contest for children. However, his father forbids participation in the competition, saying that scene, lights and makeup are not for her. Karl and Sawsan join forces in a common mission, because this is not done for true friendship!
"Mission: Star" is a story full of energy of youth, friendship and music. The film won the hearts of children and young people around the world, as evidenced by the nomination for the Young Audience Award European Film Academy. "It's about building relationships in a multicultural world, true friendship" - says the director.
