Desc: The Ruby Circle: Directed by Robert Z. Leonard. With Robert Z. Leonard, Hazel Buckham, Allan Forrest, Harry Carter. At an embassy ball Robert Carlton meets the girl of his dreams. He is attracted by an odd ring she wears, a circle of perfectly matched rubies. The following evening Carlton is jostled by an evil-looking fellow. Pausing to light a cigarette, he discovers a ring upon the sidewalk, a counterpart of that worn by the girl he loves. He places the ring on his finger. Some evenings later Robert visits a Bohemian café. A distinguished looking foreigner enters; a gleam of satisfaction appears as he catches sight of the ring which Carlton wears. He drops a note into Carlton's lap and then leaves. Carlton finds the note a sort of cryptic invitation to follow. Outside the café he meets the stranger who, without a word, leads the way. Carlton follows into an evil-looking house. Once inside the stranger leaves him. Carlton begins a tour of inspection when he hears a slight rustle. Turning, he is astonished to see the girl uppermost in his thoughts. She accuses him of being a detective. Carlton explains the affair. As she is about to help him out of the place the stranger returns with a dark robe. The girl is at her wits' end. Entering, Carlton finds himself in an underground council chamber containing thirty or forty strange figures clad like himself in long dark flowing robes. The leader of the meeting calls for the password. Carlton cannot give it. The leader, accusing him of being a spy, condemns him to death. Carlton is chained to the wall, beside a lighted bomb. To save the man she loves, the girl leaves by a secret passage and informs the police. She saves her lover from the clutches of the Nihilists, by herself turning traitor to the cause.
