Based on actual events, the story takes place in Berlin, in 1939, at the start of World War II. SS Officer Helmut Wallenburg (Helmut Berger) is instructed by his superiors to set up an elite brothel, the eponymous Salon Kitty, specially designed to serve high-ranking Nazi officials and foreign diplomats.

Wallenburg exploits his position, feeding his insatiable need to dominate and using the information he receives to blackmail his way to the top.

With the help of the brothel's madam, Kitty (Ingrid Thulin), Marguerite plots to turn the tables on Wallenburg and exact her revenge...
