The British and the American high command scheduled a top-secret conference in a desert town. On the day before the event, the Rat Patrol sights a German motorcyclist and chases him, but he gets away. Assuming that the Nazis know about the conference, Troy tries to talk the commanders out of the meeting. But instead, they assign him to be in charge of the security. Troy gets jumped while in town by a knife-wielding Arab. Sgt Roberts, one of the other "security" men, rescues Troy. Unknown to them, Roberts is a double agent planning to blow up the meeting--a fact that Troy learns.
