Once upon a time a carnivorous advertising methodist (Richard Bohringer) finds himself stuck between floors in an old elevator. The owner of the deserted building (Ute Lemper) does not help, but plays with him like a prey trapped. To get out, he threatens, attempts to seduce, to deceive, to be honest. After this confrontation for several days...

A murder is committed in the building where Aurélia Maudru, inspector of the judicial police in charge of the investigation, lives.

Georges has Down syndrome, living at a mental-institution, Harry is a busy businessman, giving lectures for young aspiring salesmen. He is successful in his business life, but his social life is a disaster since his wife left him and took their two children with her. This weekend his children came by train to meet him, but Harry, working as always, forgot to pick them up. Neither his wife or his children want to see him again and he is driving around on the country roads, anguished and angry. He almost runs over Georges, on the run from the institution since everybody else went home with their parents except him, whose mother is dead. Harry tries to get rid of Georges but he won't leave his new friend. Eventually a special friendship forms between the two of them, a friendship which makes Harry a different person.
