Arne is just coming home from his new job as a shelf packer. There he is annoyed his aunt because he's invited to the children's birthday party on Sunday. And Arne... no time at all. He has to change quickly to go to the commune party of sweet Jennifer. Besides, he's got his big gig on Saturday. Jenny must come - and that he will be fit for a child's birthday party on Sunday, he doesn't really believe.
