In 1965,
Airman First Class Adrian Cronauer arrives in
Saigon to work as a
DJ for the
Armed Forces Radio Service. Private Edward Garlick takes him to the radio station, where his attitude and demeanor contrast sharply with those of many staff members. Cronauer's show starts with his signature, "Good morning, Vietnam!", and consists of reading strictly censored news and irreverent humor segments, mixed with
rock and roll music, which is frowned on by his superiors, Second Lieutenant Steven Hauk and Sergeant Major Phillip Dickerson. Hauk adheres to strict Army guidelines with humor and music programming, while Dickerson is generally abusive to all enlisted men. However, Brigadier General Taylor and the other DJs quickly grow to like Cronauer and his eccentric brand of comedy. Cronauer follows Trinh, a
Vietnamese girl, to an English class. After bribing the teacher to let him take over, Cronauer teaches the students American slang and profanity. After the class, he tries to talk to Trinh, but is stopped by her brother, Tuan, whom Cronauer befriends and takes him to Jimmy Wah's, a local
G.I. bar. Two racist soldiers initiate a confrontation that escalates into a brawl. Dickerson reprimands Cronauer for the incident, although his broadcasts continue as normal, gaining popularity from many listeners. Tuan organizes for Cronauer and Trinh to spend the day together, but she expresses no romantic interest. While relaxing at Jimmy Wah's, Cronauer is ushered outside by Tuan, saying that Trinh wants to see him. Moments later, the building explodes, killing two soldiers and leaving Cronauer shaken. Dickerson declares the news censored, but Cronauer locks himself in the studio and reports it anyway. Dickerson cuts off the broadcast, and Cronauer is suspended. Hauk takes over the show, but his poor attempts at humor lead to a flood of letters and phone calls demanding that Cronauer be reinstated. Demoralized, Cronauer spends his time drinking and pursuing Trinh, only to be repeatedly rebuffed by her. At the radio station, Taylor intervenes, ordering Hauk to reinstate Cronauer, but he refuses to go back to work. Garlick, Tuan, and Cronauer's vehicle is stopped in a congested street, amid a convoy of soldiers from the
1st Infantry Division heading for
Nha Trang, where Garlick persuades him to do an impromptu "broadcast" before they go off to fight. The soldiers' appreciation reminds Cronauer why his job is important, and he returns to work. Dickerson seizes an opportunity to get rid of Cronauer by approving his request to interview soldiers in the field, and routing him through the
Viet Cong-controlled highway to
An Lộc. Cronauer and Garlick's Jeep hits a
mine, and they are forced to hide from Viet Cong patrols. In Saigon, Tuan learns of the trip after Cronauer fails to show up for English class, and steals a van to go after them. After he finds them, the van breaks down, and they flag down a Marine helicopter to take them back to the city. Back at the base, Dickerson reveals to Cronauer that Tuan is a VC operative and the one responsible for the bombing at Jimmy Wah's; Dickerson has arranged for Cronauer's redeployment and honorable discharge. Taylor regretfully supports the decision, knowing the risk Cronauer's friendship with Tuan would have on the Army's reputation. Privately, Dickerson tells Cronauer that he genuinely doesn't like Cronauer or his humor. Cronauer gives Dickerson one last final insult before leaving. When Dickerson tries to go after Cronauer, Taylor, having grown tired of Dickerson's petty, vindictive behavior, tells Dickerson that he's being transferred to
Guam. Cronauer confronts Trinh and convinces her to take him to where Tuan is hiding. He chases down a fleeing Tuan, decrying his actions against American soldiers. Coming out of hiding, a distraught Tuan retorts that the U.S. Army devastated his village, killing his friends and mother, thereby making the United States his enemy. Before disappearing, he comments that he still chose to save Cronauer's life at An Lộc, implying that he valued their friendship. On his way to the
Tan Son Nhut Air Base with Garlick under military police escort, Cronauer sets up a quick
softball game for the students in his English class, says goodbye to Trinh, and gives a taped farewell message to Garlick before boarding the plane. Taking Cronauer's place as DJ the next morning, Garlick plays the tape on the air; it begins with Cronauer exclaiming, "Goodbye, Vietnam!", and after some jokes poking fun at his leadership, Cronauer expresses his hope that all of the rest of the soldiers in Vietnam return home safely. ==Cast==
