This film was made, I think, late 40s -early 50s. It is about a group of 10-12 year old boys, one of whom has German parents, in London during WW2. The film follows the change in relationship between the German boy and his friends as they endure the blitz and the news coming back from the frontline. The film has a sad ending as the boy is 'accidentally' killed in a mock execution.
Anyone know the name of this film. I haven't seen it for about 30+ years but would love to see it again.
