Rebel City (1953)

"His guns were loaded for one town... one man... one roaring moment of revenge!"

Wild Bill Elliot plays gambler Frank Graham, who heads to Kansas in search of his father's murderer. This being 1864, the local military presence is more preoccupied with keeping Southern sympathizers out of the state to worry about Graham's problems. Thus, our hero undertakes the task of exposing the killer himself.
