After his wife dies in childbirth, mountaineer Jim Grimsby names his newborn daughter Bill, and raises her as a boy. Remaining a boy in name only, however, Bill soon wants to style her hair and wear the latest fashions. She soon develops a crush on the new sheriff, Waldo Whittier. Appalled at the prospect of his “son” marrying Waldo, Jim decides to test the sheriff’s grit, and so, believing that Waldo will be too frightened to come after him, he robs a casino. The sheriff does pursue, however, and, further impressing Jim, Bill pulls a rifle on Waldo to protect her father. Now certain of the sheriff’s manliness, and convinced that his daughter has not forgotten how to act like a man, Jim returns the casino’s money and agrees to let Bill and Waldo continue their courtship.
