A Persian Gulf dictator, Tufuti (Ivan Lucas), invades the country of Karifistan, subsequently plunging the United States into war. America's best soldiers respond to the call of duty. And so does good-natured bumbling yokel Ernest P. Worrell (Jim Varney). However, Ernest is anything but a conventional soldier, and he causes major military havoc. But he finds that he can help when he befriends a lost boy (Christo Davids) from Karifistan during the war.
