Elsa Ackerman is ordered by the SS to arrange a bordello on a train at the frontlines to keep up the morale among the German officers. The real reason is (of course) to spy on them to find traitors. It is an effective method and a lot of traitors are executed. When Franz, Elsa's boyfriend, is stationed on the train as an interpreter, things starts to go wrong. He falls in love with Liselotte, a spy for `La Resistance' and she convinces him to join them.
This Salon Kitty spin-off is pretty forgettable. The story is bleak and the ending is so sudden that I almost missed it. Elsa is good-looking and nicely evil, but her good properties is wasted in this far to mild flick. There are some memorable scenes though, for example when Elsa and Franz have s&m sex (boot licking) and when Elsa seduces a 20 year old virgin and then executes him. Notable is also that there's NO shower scene! Malisa Longo (Elsa) is also in Salon Kitty and Ilsa she-wolf of the SS. If you feel the need to see a nazisploitation flick (like I usually do) I'd recommend Red nights of the Gestapo, Gestapo's last orgy or Salon Kitty instead. Remember that even a bad nzispolitation is better than most movies!
