Smoldering Embers(1920)

When John Conroy's wife takes his infant son Jack and runs away with another man, Conroy becomes a tramp and goes to Alaska. Fifteen years later, he returns and learns that his son Jack is being coerced into marrying Edith Wyatt, the daughter of a congressman, in order to further the political ambitions of his stepfather, Mayor Horace Manners. Conroy makes friends with the boy, who is unaware that the congenial tramp is actually his father. Jack loves cobbler's daughter Beth Stafford, and when Conroy discovers that Manners plans to frame Jack for the loss of city funds and thus scare him into marriage with Edith, he intercedes and insures that his son receives both his rightful inheritance and the woman whom he loves. After securing the boy's happiness, Conroy slips away without revealing his true identity to his son.
