Stony (Robert Livingston) is headed for the altar with new flame Rita (Rita Hayworth) as all three Mesquiteers &mash; Tucson (Ray Corrigan) and Lullaby (Max Terhune) — try to fend off a change in policy that would allow a greedy rancher (J. P. McGowan) to target herds of wild horses. In a familiar plot, the rancher resorts to using his own trained horse to frame a wild stallion as a killer, and the boys must try to prove who is actually guilty, particularly when their friend, the sheriff, is murdered. Stony and Rita sing a duet, too, in this fairly appealing entry in the long-running series.

  Mildly recommended. Otto judiciously thinks this movie is OK, but not great.

Movie 529 for 2021.
