It is a German children's film, based on a book of the same name, and is brilliant. Opened in Germany a few weeks ago.
A group of children in Dortmund have to change their ideas, when a boy in a wheelchair wants to join their gang, and the elder brother of one gang member turns out to have burgled the shop of another one's family.
My children loved it - the elder ones have already read the book, but even the 5 year old enjoyed the film.
