 Another in the list of B-westerns made in the early 1950 s by the same people (usually changing the name of the production company on each film to get it by the previously-stung exhibitors) and easily avoided if one learns to look out for the names of Spade Cooley or Jack Schwarz. This one has undercover agent Mike Hoskins (Bill Edwards) teaming up with dude ranch proprietor Spade Cooley (Spade Cooley, what else could he play?) to put an end to The Phantom Rider and his seedy gang of diamond smugglers.
