Gene Autry gets a telegram from his brother, Ken Cooper, that he's made a big diamond strike, but there are no horses. So Gene and Smiley Burnette head off to Africa with a lot of horses, only to discover that Cooper has vanished.
It's an intriguing variation on the lost gold mine plot, but it soon devolves into one of those movies in which all the ugly stereotypes about dumb Black natives are trotted out. Burnette teaches the Cabin Kids how to sing "Dinah", director Joseph Kane is so uncaring that he doesn't bother to make the shots match on the big stunt gag (in which Autry leaps from Champion onto a runaway Conestoga wagon, and then back again with Maxine Doyle), and Ray Corrigan appears as a gorilla.
