Sometime in the past, in the parlor of his farmhouse outside of Warner Center, a small New England town, Squire Amasa Bartlett, a local magistrate, refuses to be moved by the pleas of a penitent young girl for a chance to do right. Later that day, Anna Moore, the daughter of a deceased school friend of the squire's wife Louisa, arrives at the Bartlett farm asking for work. The squire asks her if she was raised strict and is church-going. When she embarrassedly states that she has always tried to do right, they hire her. The Bartletts' son David, who wants to leave the farm for the city, is attracted to Anna. The squire, however, wants him to marry his second cousin Kate, who has just returned from Boston, so that he will stay on the farm. Lennox Sanderson, the Bartletts' suave neighbor, who has been friendly with Kate on his trips to Boston, recognizes Anna. She speaks bitterly to him, and he suggests that they pretend they have never seen each other. He later asks her to leave. When David tells Anna that because of her he now no longer wants to leave the farm, she is disturbed. After the first snow, the Bartletts plan a bonfire party for David's birthday. David drives to town with Anna, and when Cordelia Peabody, from the nearby town of Beldon, sees them together, she recognizes Anna and tells her friend Martha Perkins, a gossipy, prudish spinster, that Anna boarded at her home with a baby, but with no husband and that after the baby died, Anna left owing money, so the Peabodys kept her trunk. At David's birthday party, Sanderson, who wants to marry Kate for her money, encourages Anna to marry David. Anna rebukes him and promises to warn Kate. When David proposes to Anna, she runs to her room in tears. After Martha tells the squire about Anna's past, he immediately rides to Beldon to verify the story, while Anna tries to warn Kate, who becomes indignant at her interference. After confirming Martha's gossip, the squire, very upset, returns despite the reverend's warning that the ice is breaking up near the bridge. As a "northeaster" wind begins to blow strong, the squire arrives home and vehemently tells Anna, in front of the family, Sanderson, Martha and the constable, Seth Holcolm, that she must leave tomorrow. David, learning about the baby, asks Anna in front of everyone to marry him. When she tells the squire that the only thing she is guilty of is believing a man, David, inferring that she means Sanderson, orders him out, and they fight as Anna departs to get letters from her trunk in Beldon as proof. The squire orders Sanderson to leave, and, with Seth and David, searches for Anna. Sanderson finds her caught on a piece of ice flowing down the river toward rocks. He tries to rescue her, but they become trapped on a rapidly moving piece. As Sanderson grasps a wooden structure trying to save himself, David pulls Anna out of the river, which then carries Sanderson to his death. When the squire says that Anna cannot stay in his house, although he will see that she is cared for, David lashes out at his father, saying that his heart is filled with self-righteous bigotry, and he vows to take Anna, if she lives, someplace where human kindness exists. Louisa then convinces her husband to be more understanding and forgiving and urges him to change with the new generation. Later, at Anna and David's wedding, the squire plans to build a new wing onto the house, and David tells Anna that he is now content to live on the farm.
