The Dead Line.

Although a feud between the Harlan and Boone families has been raging for years, Mollie Powell, the Harlan's stepdaughter, is secretly in love with Clay Boone. When a young member of the Boone clan is killed during one of the battles, Clay vows that he will never touch a gun again. Branded a coward by the other mountaineers, Clay keeps his oath until Buck Gomery, one of the moonshiners, attacks Julia Weston, the daughter of another moonshiner.
