Ralph Holden has been working his mine with fuse as an explosive. One day a blast fails to discharge and a workman is badly injured by the delayed explosion. The accident preys on Holden’s mind, and he decides to try another method. Being of an inventive nature, he begins work on an electrical device which will automatically discharge the blasts. He is so engrossed in his work that he neglects his wife. Dr. Harding, a young physician in the neighborhood, is a friend of the Holdens, and his social visits are welcomed. One night Harding telephones the Holdens, asking them to accompany him to town and visit a picture show. Ralph, who has almost perfected his invention, refuses to go and asks Harding to take Katherine, his wife. On their return from the theater, a slight accident happens to Harding’s automobile, and, while waiting for its repair, Harding preys on Katherine’s lonesomeness and begs her to elope with him. She is foolish enough to listen, but does not finally consent until the next morning, when Ralph rushes off to his work without even saying good bye. Katherine then decides to leave Holden and, packing a few of her belongings, she leaves a note for her husband and leaves. That morning Holden is trying out his new device; it fails to work. As he enters to investigate, a careless workman stumbles over an electric coil, causing a contact, which explodes the charge. Holden is badly injured and blinded by the accident. A miner rides for the doctor and catches up with him at the railroad depot. He tells them of the accident. Mrs. Holden knows her husband needs her and they rush to the scene of the accident. They assist him to his home and minister to his wants. Dr. Harding calls the next morning, but learns that another physician will be engaged in his stead. The miners make a discovery of an enormous gold lode, and inform Mrs. Holden. Their future is assured, even though Holden may be hopelessly blind. The right road lies open to Katherine now and she gladly follows it.
