The second of Buck Jones' five serials for Universal, and the 23rd of Universal's sound era films, falling between "The Vanishing Shadow" and "Tailspin Tommy." This one is primarily about the efforts of lawman "Red" Davidson(Buck Jones)to save his friend "Silent" Slade (Grant Withers)from being hanged for a crime he didn't commit. It has the usual cliff-hanger endings and is padded far beyond the limits of W.C. Tuttle's original pulp-magazine story, "The Redhead from Sun Dog", in order to get 15 chapters out of what is basically a 60-minute feature-length plot. But, being based on a story by one of the better western writers of the era, it is also filled with fleshed-out characters far from the one-dimension type found in most serials of the time, and not at all in those of the 40's and 50's.
Both Jones and Withers are furnished with love interests---the lovely Marion Shilling as "Marie Maxwell" for Jones, and Margaret La Marr as "Joan McKee" for Withers,whose second-lead (and 2nd-billed)role is close to that, in importance, of the role played by Jones.
As usual, with Universal and (sometimes) Columbia serials, this one is more episodic in nature--- new plot lines get resolved within the basic plot--than those made by Republic. The latter made the best in terms of action, stunts, photography, special effects and over-all "look" of the total serial but, aside from the first and concluding chapter, everything that came in the in-between chapters looked the same.
