Hit the Saddle has enjoyed more latter-day attention than most of Republic's "Three Mesquiteers" western films thanks to the presence of young Rita Hayworth. Billed under her given name of Cansino, Rita plays a seductive saloon thrush who breaks the heart of Mesquiteer Stony Brook (Robert Livingston). Her role in the proceedings is secondary to the main thrust of the plot: Evil cattle rancher J.P. McGowan has been stealing wild horses from government-owned territory. McGowan murders a local sheriff and pins the blame on a wild stallion. The Mesquiteers (Livingston, Ray "Crash" Corrigan and Max Terhune) prove the nag's innocence, but not before McGowan is hoist on his own petard.
