The rich couple Jytte and Ole spend their lives partying and having fun. After another evening and night of partying, the couple decides to get divorced. The next day they tell Uncle Frederik, who instead proposes a bet: for a year, Jytte and Ole will live on 400,- DKK a month, so that they can experience how ordinary people live. They agree to the proposal and move into a small apartment. Gradually, they learn to cope, but give up the bet after a month. When Ole tells Uncle Frederik that they don't want to be with him anymore, Frederik unfortunately has to tell them that he has ruined their fortune. When Ole gets home, he learns that Jytte is pregnant. This changes their lives to a great extent - Jytte and Ole have suddenly found meaning in life.
