Caleb Conover, a railroad section boss, marries Letty, the daughter of a man of higher social standing, after rescuing her from harassment in a rough Italian neighborhood. By unrelenting force and tenacity, Conover becomes the corrupt political boss of his county, and the railroad president. His son Gerald refuses to work, and marries a chorus girl who is after his money and who retains her former lover. When Conover's daughter Vera returns from Europe supposedly married to a prince, Conover throws an elaborate reception and drunkenly nominates himself for governor. Anice Lanier, Conover's trusted secretary, to whom he is attracted, likes Clive Standish, a lawyer Conover cannot corrupt. After she steals compromising letters Conover wrote to his broker, Conover learns that Anice is the daughter of a man he earlier ruined.
