Jim Allen sends his oldest son Lite to inform Tom Hurley that he intends to foreclose on an overdue mortgage. The law is the worst red rag anyone can wave in a mountaineer's face, and the whole Hurley family resents the note, including Lite's sweetheart Rose Hurley. A quarrel takes place in which Lite knocks down Jud Hurley. Next, Allen and his family remove to the city to take action on the mortgage, leaving only Lite and his little brother Billy to look after the farm. In the city the Allens and the Hurleys are lined up for the case, and with much vindictiveness the nerveless little lawyer throws up the job. The business unfinished, Allen and his folks go to his brother's house for the night. The brutal Jud Hurley and his cowardly brother Ord see this, and engaging the aid of a half-breed and a negro, go to the Allen mountain home to kill Lite and his little brother. A battle takes place in which Lite overcomes the four would-be murderers. Ord reports to his folks that Lite ambushed them and shot Jud. Thus he puts the fire of Hell into old Hurley's heart and the feud is on. Ord then flees to Cincinnati. The Allens having returned, the Hurleys muster forces and attack the house. Lite seeing that his family are outnumbered goes for aid and collects friends to ride to the rescue, Lite following on foot. In the battle Lite is struck down by a stray bullet. Rose Hurley finds him and much as she hates the family the woman instinct dominates and she drags him to a doctor's hut, where she nurses him back to life. The feud becomes more deadly and the Allens and Hurleys meet for a supreme struggle on the mountain. Lon Hurley, another brother of Rose, comes upon the scene and lays a mine of dynamite attaching an electric wire. The Hurleys then vacate their position and as the Allens advance the mine is fired with great havoc. The Allens then post upon a tree a note requesting a peace conference. The Hurleys turn the paper over and write a demand that Lite Allen shall be surrendered and the feud will end. The paper is torn down by the Allens and trampled in the ground, but Rose takes it to Lite, whom she finds sitting on the edge of his bunk in the doctor's hut. In the meantime, the cowardly Ord writes to Rose confessing that his tale about Lite ambushing Jud was a lie, but the letter had been delayed by Lon, who got the letter in town and forgot to deliver it. When Lite sees the demand that he shall be surrendered to the Hurleys, he is appalled. Rose has admitted her love for him and now life is doubly sweet. However he feels that he cannot sacrifice the family and crawls to the Hurley camp. They are about to kill him when Rose rushes onto the scene waving the letter of Ord's confession. The Allens are forthwith rescued from their hut which had been fired by the Hurleys and amid general rejoicing Jim Allen and Tom Hurley clasp hands.
