Based on a true story, Robin Williams stars as Adrian Cronauer, transferred to Saigon by the U.S. Military from Crete. Cronauer becomes the host of an early morning radio show to which he adds his own hysterical brand of humor, and he isn’t afraid to poke fun at anyone, even the President. Though his show is wildly popular with his fellow soldiers, Cronauer’s superior officers are not amused by the jokes and especially the playing of banned rock and roll music over the airwaves. Riddled with sidesplitting comic bombshells and studded with hot ’60s hits, the film depicts Cronauer’s raucous Saigon adventures amidst a world gone mad.
