Nobody's Wife (1918)

Jack Darling of the North West Mounted Police is ordered to track down and arrest murderer Alec Young, whose girl, Dancing Pete, performs in the Nugget dance hall. En route to Nugget, Jack meets Hope Ross, who is caring for her sister's baby. Although the two fall in love, the outlook for a happy romance appears hopeless, because he believes that she is married and she thinks that he is an outlaw. Jack visits Dancing Pete's cabin, where he finds a photograph that proves that the murderous Alec and Sheriff Carew of Nugget are the same person. Jack convinces Carew to join him in robbing the saloon's safe, but as the sheriff takes his share of the money, Jack exposes him to the angry townspeople. Carew tries to escape, but the Mountie overtakes him, following which Jack and Hope delightedly learn the truth about each other.
