The Trail of the Lonesome Pine (1923)

June Tolliver, whose family has long feuded with the Falins, falls in love with engineer John Hale when he comes to their mountain town. John sends her to the city to be educated with the promise of marriage when she returns. Because John is appointed deputy he tries to remain neutral, but he finds the Falins supporting him when June's Uncle Rufe is accused of murder. June is called to testify during his trial but does not perjure herself for Rufe's sake. To prevent a Tolliver from being hanged, Jud Tolliver has Rufe shot. John is also injured, but June's pleading finally brings an end to the feud.
