Anderssonskan's Kalle is the typical 'Söderkis'. It's a boy growing up on Söder in Stockholm and he is very fond of practical jokes. His mother sees him as a good natured boy but his victims, mostly the local policeman and two old crones in the same house, see him as the devil himself.

A group of young people gathered on the countryside to celebrate midsummer dancing, drinking and romancing. And some fighting too. Followed by more violence, jealousy and guilt. On the journey home one of the cars the travel in collides with a bus.
