Marshal Rocky Lane and prison warden John Hamilton cook up a plan to allow young Bill Henry to break jail to see if he'll locate the others in the bank robbery he was convicted for. It's a daring plan and if it doesn't work their careers will be circling the bowl.
But trailing Henry convinces Lane that the escapee just might not be guilty at all. In fact banker Roy Barcroft just might be involved in some wholesale swindling and won't stop at anything to make a quick buck including murder.
Marshal Of Cedar Rock was a good product from Republic Pictures and their dwindling supply of movie cowboys and a lessening demand for these B films which the audience could get on the small screen.
Another reviewer was right it did look like the cast of Superman went on hiatus to do this movie. Besides John Hamilton, Robert Shayne plays a phony railroad agent and Lois Lane number one Phyllis Coates plays Eddy Waller's niece and the girl that Bill Henry was courting and who Roy Barcroft was trying to move in on.
Barcroft plays a very crafty villain, but something unforeseen does him in. You have to watch Marshal Of Cedar Rock to know what that is.
