Whispering Women (1921)

Dave Hartley operates the largest lumber camp in his section of the Northwest. He has a lovable wife and charming little daughter who is loved by little Bobbie. Dave is called to his camp. While at camp a mysterious stranger visits the community and the babbling tongues of idle gossipers charge Mrs. Hartley with undue intimacy with him. This gossip reaches Hartley, who sets out to learn of his wife's disloyalty for himself. Hartley is exhausted in the dense woods and is forced to hide. The wolf pack arrives. Meanwhile little Bobbie and Dolly are lost in the forest and spy Hartley. Dolly's faithful dog, Brindle, sensing danger, ... arrives ... just as the wolves are about to make a final plunge for the three. He fights off the wolves, killing one. Later Hartley learns ... that the mysterious stranger was none other than her [Florence's] brother, who, having committed a crime, comes to his sister, Mrs. Hartley, for help.
