The Price of Her Soul(1917)

Gun Connor decides to fight the drug evil, after learning that his brother is a victim. He redoubles his efforts when he learns that the father of the girl he loves is the manufacturer and chief distributor of the drug. In his effort and with revenge as a motive he becomes responsible for Ailene Graham, daughter of the head of the drug gang, succumbing to the influence of the deadly narcotic. He works every angle to torture her father into realizing the dangers he has been dealing out to others, through daily letters in which the girl's growing helplessness is pointed out. Finally, when she becomes a helpless victim of the drug, Connor takes her to her father, who, upon seeing that his dealings in the drug have reached his own fireside, refrains from the further dealings, and months later, joins his daughter in the mountains, where Connor has taken her and his own brother. Completely cured, Connor's love is rewarded. A cure is effected and contentment reigns.
