When a radio station's management announces that there's going to be an upswing in commercials on the air, with a strong emphasis on ads for the U.S. Army, the anti-establishment deejays form a united front against the "suits." With station manager Jeff Dugan's (Michael Brandon) unofficial approval, the other employees hijack the station, playing the kind of music they like before the authorities can arrive. Martin Mull appears in his feature-film debut as a zoned-out record spinner. In addition, the film includes live appearances by the likes of Tom Petty and REO Speedwagon & live performances by Linda Ronstadt and Jimmy Buffett.
