The Man from Hell's River (1922)

Though engaged to Pierre, a member of the Royal Mounted Police, Mabella, a girl living at a Canadian fur-trading post, is forced to marry Gaspard, a vicious half-breed who has incriminating evidence about her father, Lopente. Pierre is distressed; Mabella, brutally mistreated and neglected by Gaspard, goes to the police station for protection. Gaspard, however, abducts her and forces her to go away with him on a dogsled. Pierre discovers that Gaspard is wanted for a crime, and pursues them; Rin-Tin-Tin, his dog, kills Gaspard, effecting the rescue of Mabella. Father La Croi reveals that Mabella, an orphan discovered during a snowstorm, is not of Indian parentage, and she is happily united with Pierre.
