Trude and Willi Lorenz have had an exemplary marriage for 24 years. Their daughter Gitta takes them as a role model for herself and her fiancé Peter. But appearances are deceptive. Willi cheats on his wife with the young secretary Helga. He is a department manager in a heavy engineering company and travels a lot on business. Trude also has a busy working day as a divorce judge. Obviously, family life has been neglected as a result, and now Trude herself is facing a problem that is very familiar to her from her job. An alderwoman has drawn her attention to her husband's infidelity, and a visit from Helga, who demands that she give up her husband, forces her to make a decision. Willi Lorenz has cheated on both women. In a discussion, he finally confesses to Trude and their life together. The fact that it doesn't come to the "Lorenz divorce case" is also thanks to the sincere, compassionate driver Schliffke, who tactfully opens the eyes of his boss Lorenz and the young Helga.
