Reinhold Schünzel plays the rigid representative Traugott Bellmann, who publicly condemns the low morals of the night life. Although Belmann's stance is supported by his wife, he is strongly opposed by his father-in-law, a champagne manufacturer. But when he inherits 500 000 Marks in cash and the infamous nightclub "Der Himmel auf Erden" ("Heaven on Earth") from his deceased brother, Bellmann really gets himself into trouble: In order to fulfil his brother's will - and to get hold of the money - , he has to be at the club every night at 9 pm.
