A tough U.S. sergeant and his sidekick roll into a demoralized firebase, where they attempt to rebuild morale and fortifications amid a climactic battle with the Viet Cong.

The film's thin veneer of social propriety (the story of how the VietCong came under Hanoi's control) is merely a cover for a rolicking old-time battle tale, complete with a hard-tack sergeant, his rebellious sidekick, and a demoralized base that needs to be whipped into shape before the VietCong attack.—Binyamin Appelbaum

Vietnam, 1968. A veteran Marine Sergeant Major inadvertently ends up commanding a remote firebase, Firebase Gloria, just as the Tet Offensive is about to begin. He knows a very large Viet Cong force is headed for the base, outnumbering the defenders several times over. The odds are stacked against the Marines and they will have to hold out until help arrives. If it arrives.—grantss
