Because the film was produced at the time when Czechoslovakia was occupied by the Germans, the credits appear in German (left side of the screen) and Czech (right) at the same time.Zuzanka (Natasa Gollová) can finally stop toiling away at washing dishes at hotel Mercur after a distant aunt has bequeathed her her own hotel - Blue Star. She proudly marches over to the luxury hotel in the center of town and immediately begins to change the personnel. Because this involves the facilities belonging to a joint-stock company, which no one can inherit, she is considered insane. It comes out that her inheritance is in reality a small, shabby little hotel of the same name in the IV town district. The personnel are three unemployed youths who in this way work off the money they owe for rent. The first guest is wealthy Vladimír Rychta Rohan (Oldrich Nový), whose parents spent their honeymoon in this very hotel. He wants to celebrate his wedding there, with which his fiancée Milada (Adina Mandlová), who is waiting for him at the luxurious Blue Star, does not concur.
