Popular radio characters Lum (Chester Lauck) and Abner (Norris Goff) step out from behind the microphones and onto the big screen in this wacky romantic comedy. Lum wants to impress lovely lady Geraldine (ZaZu Pitts) who he thinks would be the perfect wife. Geraldine has a thing for knights in shining armor. That leads Lum to believe that in order to secure her affections, he has to play the part of "Lancelot" by rescuing Abner from a string of "accidents." Obviously, things aren't going to go as they plan, but it's all in good fun!
