When Hell Broke Loose (War 1958) Charles Bronson 720p

Near the end of the war in Germany, GI Steve Boland, a self-described "sharp operator", meets a German girl, Ilsa, and they fall in love. Ilsa's brother Karl, whom she has not seen in three years, and his buddy Ludwig visit Ilsa. Karl proudly informs her that he and Ludwig are "Werewolves", a group of Nazi assassins parachuted behind Allied lines for the purpose of assassinating Allied High Command officers. Ilsa and Steve go to U.S. Army Intelligence with this information, where Steve is immediately arrested for being A.W.O.L. Captain Melton of Army G-2 intervenes on Steve's behalf, as G-2 has had a suspicion about the existence of the "Werewolves" but no concrete info before now.
