Theatrical agent Waldo Main is inducted into the army, and turns his now clientless agency over to his secretary Dottie Duncan. Dottie decides to organize an all-girl orchestra to fill the void caused by so many orchestra members being called to service due to WWII, and joins struggling singers/songwriters Sally Richards and Sue Ford in this endeavor. Dottie's screwball schemes to get engagements for the group often lead to disaster.

Socialite Cathy Abbott is working in the chorus of a Broadway show instead of being enrolled at an exclusive girl's school as her parents think. When the show closes, she brings two of her chorus friends home with her. In addition to trying to make her friends acceptable to the snooty society of which her family is part, she is also being blackmailed by a rival.

A group of ranchers, led by Colonel Arnold and Ward Gordon, are drilling an oil well but getting fierce opposition from an unknown gang of outlaws. Eastern promoter J.B."Dude" Dawson, is behind the gang as he is out to prevent the co-op members from striking oil before their lease expires, so he can secure the property for his company. When Ward, with the help of Arnold and his daughter Sally, arranges for a new driller to be brought in, the replacement man is killed and one of Dawson's men takes his place.

Unusually elaborate for a PRC film, Minstrel Man is a lively musical drama built around the talents of veteran vaudevillian Benny Fields. The star is cast as Dixie Boy Johnson, who rises from the ranks of minstrel shows to become a top Broadway attraction. On the opening night of his greatest stage triumph, Dixie Boy's wife dies in childbirth. Profoundly shaken, he walks out of the show, leaving the baby to be raised by his showbiz pals Mae and Lasses White (Gladys George, Roscoe Karns). The kid grows up to be an attractive young woman named Caroline (Judy Clark), who follows in her dad's footsteps by billing herself as-that's right-Dixie Girl Johnson. This leads to a tearful reunion between Caroline and the father she'd long assumed to be dead. If Minstrel Man seems at times to be a dress rehearsal for Columbia's The Jolson Story (1946), it shouldn't surprising: the PRC film was directed by Joseph H. Lewis, who went on to helm Jolson Story's musical highlights.
