The Commanding Officer (1915)

When Colonel Archer, the military post commanding officer, refuses to loan money to his second-in-command, Captain Waring, Waring gets the money from Brent Lindsay of the nearby mining town, in exchange for his note. Both Waring and Lindsay court Floyd Bingham, the daughter of a retired colonel, but Floyd learns that Lindsay is involved with Queen, a dance hall girl. Following the urging of her father, Floyd marries Archer, who has two children left to him by his dying sister, whom Floyd loves. When Lindsay continues his attentions to Floyd, Archer quarrels with her and leaves to go hunting. Floyd goes walking in the woods with Lindsay and his kiss is photographed by Waring, who attempts to blackmail Lindsay. When Lindsay is found dead and Archer, who suspects Floyd, is arrested, the men from the mining town almost lynch Archer, but Queen, who witnessed the murder, clears him.
