A Day of Fury (1956)

A Day Of Fury stars Jock Mahoney as town marshal Alan Burnett, whose life is saved by a stranger he meets on the trail. His rescuer turns out to be Jagade (Dale Robertson), a gunslinger just returned after years away, who finds when he gets into town that he can’t abide the peace that has been settled between “his” people (i.e. the saloon-keepers, gamblers, etc.) and the righteous, “respectable” folk.
