In 1930, Lemuel "Lem" Siddons (Fred MacMurray) is a saxophonist in a traveling band who dreams of becoming a lawyer. When the band's bus reaches the small town of Hickory, Lem suddenly decides to leave the band and settle down, finding a job as a clerk in the general store owned by John Everett Hughes (Charlie Ruggles). At the town civic meeting, Lem again notices Vida Downey (Vera Miles), a bank teller whom Lem had seen on his first day in town, and eventually attempts to woo away from her boyfriend Ralph Hastings (Elliott Reid). Lem notices Vida crosses off the YMCA and the 4-H from her list of three possible organizations to keep the town's boys off the streets, leaving only the Boy Scouts, and he decides to suggest and volunteer to become Scoutmaster of the newly formed Troop 1.
