In a secret camp in Nazi Germany, cruel experiments are conducted for "the selection and improvement of the Race." Female prisoners are forcibly mated with German soldiers and subjected to strange sexual tests. Nazi Sergeant Kruber falls in love with a camp inmate, the lovely French prostitute Mirelle. When Kruber is forced to participate in a perverse operation ordered by the camp's commandant, the sergeant joins forces with the female inmates to exact revenge on their sadistic overload.
Banned in the past for its controversial subject matter, Sergio Garrone's 1976 exploitation horror flick uses a World War II Nazi camp as the setting for the torture, rape, and murder of its female victims. Campy, soft-core scenes show cruel Nazi officers conducting strange and sadistic experiments on the female prisoners. Karma takes its toll, however, when Sergeant Kruber unexpectedly falls in love with a French prisoner named Mirelle (a prostitute), and joins the ladies for the ultimate act of revenge.
