A large Panzer unit has a map showing a strategic oasis occupied by the Eighth Armored. U.S. Intelligence wants the map exchanged for a phony one which would show the oasis as empty. Accompanied by a veteran map expert, Sgt. Griffin, Troy and his men start into the German HQ. At midnight, using bows and arrows for weapons, they go into the area but Griffin has a heart attack and the team is trapped in the commander's office. In the end, Troy bullies the ""expert"" into keeping up the effort until they are finally able to finish the mission, whereupon Troy ends up endangering his own life to get Griffin out of the town.
