Károly Aszlányi

Bimbi, aka Takács Klára is unemployed. She lives in a sublet and has no idea how she will live and pay her bills. But luckily for her, the previous tenant, who had a letter of recommendation for the director of Tormássy Works, has now been put in a mental home. So he can apply for a job with the "unused" letter of recommendation. Since the letter says that the "lady with a bit of a bug" will not get a job, she can go to the son of the CEO as a typist's assistant.

The nephew of a wealthy nobleman, convicted for a forged check, is replaced in prison by a poor engineer. From the exchange of people derives a chain of misunderstandings and messes that ends out well.
