Nathalie: Escape from Hell (1978)

Sinopsis

When a Russian doctor (Patrizia Gori) falls foul of the Nazis, she finds herself imprisoned at Fort Stilberg, a luxury brothel for German top brass where the women are overseen by sadistic SS officer Helga Hortz (Jacqueline Laurent). The doctor's medical skills bring her to the attention of Nazi Lieutenant Erik Mueller (Jack Taylor), who saves the lovely lady from becoming one of the establishment's 'hostesses' by assigning her to the infirmary.
