When their car stalls, Arnold and Mabel, a middle-aged couple on a holiday in Tennessee, meet country singer Marty Robbins, who gives them tickets for the Grand Ole Opry in Nashville. Thinking they are attending the opera, the couple are shocked at the casual attire of the audience and by the music itself. Arnold enjoys the show, however, and, eager to meet some of the singers in person, goes to watch the making of a film in which a number of the singers are appearing; but Mabel returns in disgust to New York. The couple are eventually reconciled at a party to celebrate completion of the film, and they pay a return visit to the Grand Ole Opry.
