Sergeant Thomas Highway is an old-fashioned Marine Corps sergeant who is out of step with the new-fashioned military and returns to his old outfit as a gunnery sergeant, where he runs afoul of 1980s-style superior officers to whom the words "Gung Ho" are foolish anachronisms. But through his tough tutelage, Highway's lackadaisical platoon is whipped into a first-rate fighting machine, favoring teamwork over such New Age concepts as "self-fulfillment." Finally, the men prove their mettle during the invasion of Grenada.
The Griswold family set out in high spirits, ready to spend their vacation driving from Chicago to Walley World on the West Coast. But the trip soon falls apart, with mishaps and bad luck at every turn. When they finally arrive at Walley World, and the park is closed for maintenance, Clark Griswold snaps. He takes a Walley World security guard hostage, in one last attempt to deliver on his promise to his family of a Walley World vacation.
