After a major German advance, Saunders, Little John and Doc find Sgt. Larkin, who they know, then encounter an unruly Pvt. Henry Murfree, who they don't. Murfree constantly accuses them of being German infiltrators, and there are other indications that German SS are infiltrating, under the command of SS Hauptmann Klepner.
