Johnny Prentice, a bandleader in Chicago with a bad temper, alienates some of his musicians and is in danger of losing custody of Half Pint, his son. He hires Linda Rogers to be the boy's tutor.
After being encouraged by Linda to pursue his dream of playing at the Cocoanut Grove nightclub in Los Angeles, they pack up friend Dixie's new trailer and head west. At a trailer park, they run into Hula Harry and hear a song he's composed. To his amazement, Johnny discovers that not only is Harry very talented, Linda is, too.
The trailer breaks down in Kansas, but the good news is that garage owner Bibb Tucker is a talented fellow as well. He is invited to tag along. When the group reaches L.A., the club date has mistakenly gone to another band. Worse yet, Johnny's apparent flirtation with Hazel De Vore leads to Linda boarding a bus and leaving for home.
Discovering the mistake, Johnny's musicians take matters into their own hands and keep the other band captive, Johnny goes after Linda and gets her back in time for that night's show.
