Fired for crashing his aeroplane into his employer's ranch, Tom Mix is elected sheriff in a town with, as a title stated, "a high mortality rate among sheriffs." Mix, of course, prevails against almost impossible odds, at one point cornering a gang of cutthroats holding leading lady Dorothy Dwan captive in the crater of a volcano about to erupt.
Unfortunately the movie Silver Valley is not yet available on HBO Max.
