Zappa(1983)

Denmark, 1961. Bjørn, a middle-class boy in his early teens, wants to be accepted by Steen, a bullying peer of his with wealthy but freezingly cold parents. Bjørn's other good friend is Mulle, a cheerful and more childish working-class boy. All three seem friends at first, but gradually Steen starts pushing Mulle away while pulling the impressionable Bjørn with him towards more and more violence.
