A man with a beautiful wife has grown too accustomed to her, as men do, even bored. Johann's wife Bella solicits her husband's attention to no avail. He prefers even the newspaper to her company. In the evening however Johann has other plans. He likes to slip out to Maxim's to dance, flirt and seduce.
While Johann is ignoring her, Bella - as attractive women, married or not, always do - has an admirer. In this case, the admirer is their children's tutor Ulrich.
When Johann has disappeared to Maxim's, Bella calls Ulrich to the house. Ulrich sees his chance and goes in for the kill, hoping to seduce Bella the same evening. But for the moment, Bella cannot bring herself to betray her husband. Ulrich has a backup plan; he wants to disguise Bella and take her out to Maxim's where she can see Johann's womanizing for herself.
Ulrich's hidden agenda is that when Bella has seen Johann's infidelity, she will be easy prey for himself.
Curiously, when Ulrich and Bella reach Maxim's, Bella makes a tremendous impression on all the men there, including her own husband. Johann leaves all the other delicious ladies and starts courting his own Bella. But Johann doesn't realize that the gorgeous woman he is wooing is his own wife.
When Ulrich sees his plan falling apart, he makes arrangements for Johann to be arrested and put in jail.
Johann has these strange bat wings with which he flies away in the night. When he is in jail, Bella drops by with the magistrate and seduces him into allowing her into Johann's cell. When in the jail, Ulrich brings Bella a giant pair of scissors and Bella cuts away Johann's bat wings. After his release from jail, Johann is grounded at home where he gets carpet slippers for a future of domestic bliss.
