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.
