A Day of Fury(1956)

The story of Jagade... last of the maverick killers!

Town marshal Alan Burnett life is saved by a stranger he meets on the trail. His rescuer turns out to be Jagade, 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.
