Bonnie, an innocent orphan girl, is bullied by Bull Dorgan, the crude foreman of the lumber camp who frequents the saloon that her foster father owns. One day, playwright Arthur Wharton arrives in town, brokenhearted because the woman he loved, Elinor Grenville, married another for money. To protect Bonnie from Dorgan, Arthur marries the girl and then leaves her in the care of his sister Charlotte while he travels to Japan. When he returns, Elinor, now a widow, decides she wants Arthur back and so endeavors to estrange the couple by hiring a man to compromise Bonnie.
