Otto Wanz

The manufacturer Xaver Frey is forced into bankruptcy by his bank and decides to commit suicide in a sleeping car from Vienna to Venice. There he encounters the sleeping car attendant Horak, who is about to retire and who uses every legal and illegal means to prevent his suicide.

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.
