20 volunteers agree to take part in a seemingly well-paid experiment advertised by the university. It is supposed to be about aggressive behavior in an artificial prison situation. A journalist senses a story behind the ad and smuggles himself in among the test subjects. They are randomly divided into prisoners and guards. What seems like a game at the beginning soon turns into bloody seriousness.

Paul, shy, and not exactly what one would call a ladies man, checks his answering machine and gets a surprise message from a woman named Sandra. Great, except that he knows three Sandras: one he'd love to hear from, one he'd hate to hear from and a third he'd never expect to call him. Paul desperately wants to find out who is the woman who called and enlists the help of his close friend, who is a ladies man. Marc, though very busy himself and eager to pursue his business, agrees to help. And so begins an urgent investigation. Nothing ventured, nothing gained.

So far he has earned his living as deputy editor-in-chief at the Grevenbroicher Tagblatt, but actually Horst Schlämmer had always guessed: he was destined for something bigger - too much bigger. Without further ado, he therefore quits his old job, founds his very own party and thus starts his rush to the chancellor's office. While the election machinery is quickly started and soon picks up speed, only two questions remain unanswered: Is Horst Schlämmer ready for Germany? And is Germany ready for him?

While getting a beer in the police canteen, Docker is spied on by the BKA for a special secret mission: an attack is planned on an Indian maharajah during his visit to Germany. In the operation 'Falscher Hase' (False Rabbit), Docker is to serve as convincing personal protection. Shortly afterwards, he finds himself disguised as a double in an ambassador's limousine - opposite him is the maharajah's little prince and his beautiful Italian chaperone Selinda, with whom he promptly falls in love. When he brags to his colleague Dretzke about the whole affair, it leads to a chain of dramatic but also wonderfully funny events in which the model boys find themselves in dire need of an explanation.
