Ms Kathleen's

Screen 5 of 26

One of Professor Unrat's most formidable adversaries is the 17-year-old Lohmann, whose quick-thinking allows him to escape punishment and enrage his teacher. Raat discovers a poem in the student's notebook addressed to ‘Fräulein Rosa Fröhlich’, whom he proceeds to track down. At a cabaret called the "Blue Angel", he finds a placard promoting the ‘barefoot dancer’ Rosa Fröhlich. Trying to avoid his students, Raat finds himself in the dressing room of the dancer, where he commands her to stop corrupting his students and leave town immediately. In response, however, she offers the professor wine and attempts to charm him.

The next morning sees a cease-fire between the students and the professor; he is afraid of being made a fool of in the classroom and they are afraid of being written up by the principal. That night, he returns to Rosa and calmly explains how unacceptable it is for her to accept wine, champagne香槟 — sparkling wine, and flowers from students. Rosa seduces the professor, beginning a relationship with Raat that sees him catering to her every wish: expensive restaurants, new clothing, a furnished flat, even sorting her laundry.

Eventually he is fired from his position, marries Rosa, and discovers she has a daughter. After two years of this marriage, Raat is financially ruined. A friend of Rosa's suggests that Raat give ‘lectures’, which serve as a cover for Rosa to discreetly entertain male clientele in the professor's formerly respectable home.
