What do grown-ups actually do at night? Little Kuno has been asking himself this question a lot lately. One day, the curious six-year-old decides to get to the bottom of it and sneaks outside his house at night. He wanders around the streets aimlessly and experiences some very exciting things.
Post-war Germany: Like so many other women, Gerda Krause has lost her husband during the war and has to fend for herself and her two children. She finds work as a seamstress but refuses the offering of her department chief Zimmermann to upgrade her qualifications. One day she meets Uschi, an old friend of hers, whom she has helped with schoolwork before the war and subsequently lost track of. The reunion reminds Gerda of her childhood dream: to become a teacher. Thus, she decides to enroll at university to make her dream come true.
The friends Jochen and Gerd both work at the fashion boutique "Saxonia", which has only recently designed a new collection. Therefore, Jochen and Gerd are shocked when they meet two young ladies during their well-deserved holiday who are already dressed in two of the new pieces. And as if that was not enough, they pass the creations off as their own, even though they are employed at the competing company "Berolina". Naturally, the two men refuse to let the matter rest, although they do not actually want to raise a quarrel with the pretty ladies. After some turbulent entanglements they become aware of the foolishness of their squabbling and, eventually, the four of them present the disputed designs as a co-production at the fashion fair in Leipzig.
