Devoted mother and wife Muriel Barnes is married to prominent businessman Judson Barnes. When Frank Craftley, a promoter of fake mining enterprises, gains social access to her home, he believes he has seen Muriel before, and realizes that his partner, miner Jack McGoff, has a photograph of her as Cora Lamont. McGoff had married Cora in Alaska while he already had a wife, and forced Cora to become a dance hall girl. Cora had escaped by shooting McGoff in self-defense. Craftley works upon Muriel's fears until she persuades her husband to go west to examine Craftley's claim. McGoff visits Muriel, who has set up a ruse. Aware that there is a policeman below, Muriel arranges the room to appear as if there had been a robbery, and then screams for help. McGoff is killed after opening fire on the policeman. The shadows of Muriel's past are dispersed.
