What is the name of the person whose brother plans a terrible revenge?
As described in a film magazine, Sheila Hepburn, the half-sister of Alan Hepburn, is the daughter of a Japanese mother. While visiting Alan, who works in Tokyo, she attends a festival with her Japanese maid while wearing a Japanese kimono. There she meets the wealthy Arai Takada, who is taken by the mysterious woman. Alan has dishonored and betrayed O'Mitsu, and her brother Arai plans a terrible revenge. Alan loses heavily at cards to Arai and, to forget his losses, accompanies Arai to his country home. There Alan is about to be thrust into a pool of quicksand to die when Sheila appears, having been warned of Arai's plans. Dismayed that the woman he met at the festival is Alan's sister, Arai sees that she and Alan do not meet, but later agrees to release her brother as Sheila wins Arai's love and respect. At that moment Alan appears, having escaped from his prison, and strikes Arai down. Sheila bursts into tears and runs to the fallen man, and Alan, seeing his sister responding to the "call of the east," departs.
