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.
