The Dead Line (1920)

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. Clay comes to Julia's defense, and during the fight the Harlans are arrested and jailed, thus freeing Clay and Mollie to live their lives together in peace.
