Alternative love stories, physical entanglements of erotic language. In 1957, Max (DirkBogarde), a former Nazi officer, became anonymous as a midnight gatekeeper at a hotel in Vienna. One day, he met Lucia (Charlotte Rampling), the wife of a famous conductor, and the past was overwhelming. It turned out that Lucia, a survivor of a Nazi concentration camp, was Max's sex slave and his lover, and Max kept thinking about her. Max took advantage of Lucia to go out to perform, reunited with Lucia, and immediately took her to her apartment, and the two quickly restored their former relationship. At the same time, Max's Nazi remnant group was also looking for Lucia to get rid of this powerful witness, and Lucia's husband called the police because his wife was missing. Max had no choice but to hoard a lot of food in the apartment, and Lucia stayed at home, comforted each other through sex, forgot the plight of reality, and waited for the coming redemption or destruction.
