In 1957, in the town of Coburg, as in most of West Germany, reconstruction is the watchword, and Coburg's élite all benefit: the mayor, the police chief, the bank president, the newspaper editor and above all, Schuckert, a property developer who owns the brothel the other men frequent. His favourite employee is its singer, Lola.
This cosy arrangement is threatened by the arrival of the high-minded and cultured von Bohm, a refugee from East Prussia, as the new building commissioner. Divorced, he hires a woman with a young granddaughter as his housekeeper and devotes himself to his new job. One day, while he is out at work, his housekeeper shows her daughter his house. It is Lola, who decides she wants to know this interesting man and soon attracts his attention under her real name, Marie-Luise. Unaware of her night job or that Schuckert is her daughter's father, von Bohm proposes to her, but she warns him off. When he is finally taken to the brothel, he discovers the truth about her.
In the meantime von Bohm has been collecting evidence of Coburg's widespread corruption, including building permits masterminded by Schuckert, and decides to put a stop to it, but nobody is interested. Unable to change the system, and still in love with Lola, he marries her with Schuckert's blessing. As a wedding gift, Schuckert gives the pair the deed to the brothel and, while von Bohm is taking a walk after the church ceremony, takes the bride to bed.
