A group of young unemployed people from Le Mans (France) decide to create a new political party.

In 1950s Copenhagen, Jens is a law student with a part-time job in a law firm. He lives at home and is more or less engaged to Lis. Jens' life is very regular and organized until he meets slightly older Erhard, a head clerk at the firm. Erhard lures Jens into the mysterious city nightlife, and from now on, Jens' life changes. The engagement is broken off and his education is neglected.

Jacob and Finn run their low-budget private-eye business out of an auto salvage yard. Usually they are woefully incompetent, and on occasion they are inventive, like the time they find a boat captain's dentures. They're broke, so when Finn comes to the attention of a local hospital as having very healthy organs, Jacob is willing to help a corrupt doctor and his gold-digging nurse sell Finn's heart to a dying sheik in Switzerland. Finn rebels, so Jacob plots to substitute a pig's heart; then Finn gets attached to the pig and won't hear of its slaughter. As the sheik's health deteriorates and the doctor gets more desperate, Finn is in grave danger. Jacob has another plan.
