The Silent Vow (1922)

In a prologue, Jim Gorson, a handsome woodcutter, persuades the wife of Richard Stratton to elope with him. Twenty years later, Dick Stratton, Richard's son, a Northwest Mounted Policeman, is ordered to capture Bill and Doug Gorson. Circumstantial evidence points to the Gorsons as murderers of Dick's father, but the Gorsons escape, leaving behind their father wounded by the Mounties. Elizabeth Stratton, who has adopted two orphan children, Anne and Ethel, is abducted by Bill and "Sledge" Morton, a czar of the river district. Meanwhile Dick tracks down Doug Gorson, but he releases him on his pledge to aid in rescuing Ethel and Anne. Following an extended fight with Morton and Bill Gorson, the Gorsons explain that the elder Stratton died of heart failure; the 20-year-feud is ended, and after the death of Elizabeth, Dick and Doug return to civilization with the girls.
