Robert Duvall guest stars as Peter Halsman, a German medic who is captured while Hanley (Rick Jason) and his squad prepare to knock out an enemy observation post. Though Saunders (Vic Morrow) strenuously objects, Halsman is forced to accompany the men while they carry out their mission. As the situation intensifies, Halsman finds himself in conflict with his medical ethics--especially when he must weigh the lives of his captors against those of his fellow Germans. ~ Hal Erickson, Rovi
