A movie director is approached by his old math teacher with a great movie idea: the Devil declares that the Earth is hell. The director rejects the idea, but subsequent events in the life of a writer, a friend of the director's, and a young prostitute he loves seem to prove the math teacher's idea.
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.
The kid Anderssonskans Kalle is a menace to his surroundings and this time he uses nails, fireworks and sneezing powder.
