The musician Udo Lindenberg (played by himself) is kidnapped during the party after a concert. Nobody realises this until the next day, when he doesn't show up in time for a rehearsal. Since the police believes this is only a promotion gag, private eye Kuhlmann (also played by Udo Lindenberg) has to be hired to find him in time.
