The Hopkinses are a family of squatters struggling against the wealthy landowners or "hilltoppers." When Jerry Hopkins is unjustly imprisoned, his young wife and baby die as a result of the shock, but his sister Polly maintains the faith that has been instilled in her by her grandmother. Later, Polly meets hilltopper Robert Robertson and the two fall in love. Their courtship is disrupted when Robert's sister Evelyn is blackmailed by Oscar Bennett, the man to whom she is secretly wed. In her efforts to help Evelyn, Polly falls under unjust suspicion. Meanwhile, MacKenzie, one of the vindictive landowners, arrests Polly's father and sends her brother to an orphanage. Devastated by these events, Polly's grandmother dies of grief and Polly swears revenge. She has Evelyn kidnapped and brought to her cabin, but the memory of her grandmother prevents Polly from harming her tormentor. Polly's nobility inspires Evelyn, who exonerates Polly, thus clearing the path for her marriage to Robert.
