Truitt is a country lad who conceives an overpowering ambition to become a great power in the steel industry. In his daydreams he often pictures the peaceful valley in which he was born and reared--filled with belching chimneys and vast furnaces under his complete mastery. As a beginning he bids goodbye to his little country sweetheart and enters the employ of a steel mill in Pittsburgh. He starts in at the lowest form of manual labor, but quickly is raised to a position as gang foreman, and soon afterwards becomes a skilled worker in the mills. He boards with the family of a shop foreman. The shop foreman's daughter falls in love with Mark and gives herself to him unreservedly. Truitt fights his way on relentlessly. He becomes superintendent of the mill and then forms a new corporation with one of the younger partners of the firm. He deserts the girl of the mill, returns to his old home, marries his first love, and sees the realization of his life's ambition, in the construction of his own great steel mills in the quiet valley in which he roamed as a boy. His wife becomes a mere social butterfly and the couple are estranged. There is a divorce. Alone in his great mansion, monarch of all he can survey from his window's outlook, Truitt at length realizes how hollow a victory he had gained in a life of power without love. He seeks out the girl of his days in the Pittsburgh steel mill, finds her love steadfast, and makes her his wife.—Moving Picture World synopsis
