During a skirmish with the Germans, Troy suffers a concussion from an explosion. He ends up alone and lost in the desert. By the time he is found he has a terrible case of sunblindness. Unknown to Troy, though, his ""rescue"" has been by a German unit that is pretending to be Americans so they can coax Troy to tell him where the rest of the Rat Patrol is. Dietrich is the engineer behind this ploy.In the end, recovering from the sunblindness in the nick of time, Troy escapes.
