The Cave Girl (1921)

Margot Sperry, who keeps house for her guardian, a professor who wants to revert to primitive modes of living, finds it difficult to find food in the winter wilderness and resorts to pilfering from the Bates's winter camp. Divvy, engaged to a girl he does not love, meets Margot on one of her raids and falls in love with her. Baptiste, a half-breed employed by the Bates family, is discharged for stealing and burns the camp, driving the family to refuge with Margot. Elsie, hoping to regain Divvy's affections, dresses in boyish clothes similar to Margot's. Joining forces with Baptiste, they capture Margot, and Baptiste takes her in a canoe downstream. Realizing her mistake, Elsie warns Divvy, who bests the half-breed and then rescues Margot from the falls. A lost film.
