East of Berlin (1978)

Young German officer Erich von Strasser (Jean-Marie Lemaire) leaves his fiance and heads off to war. Stock footage of Nazi desert warfare plays and before you know it Erich is back in Germany, recipient of the Iron Cross and a national war hero. First stop the whorehouse then, naturally. Where he bumps into his fiance, awkward. Cue a flashback showing how/why she ended up there and after a night of passion Erich goes to his superiors asking she be freed. Unfortunately, for reasons still unclear to me, she is shipped off to another location and Erich sets off in pursuit.
