The Iron Ring (1917)

Bess Hulette is disappointed and feels ignored when her husband Aleck accepts a partnership in an ad agency owned by Stephen Graves. She tells her neighbor, Mrs. Leonard, about her predicament. One day a young woman, Dorothy Delamore, is injured in a car accident just outside the Hulettes' home. Bess meets Dorothy's brother, Jack, who is attracted to her. Noticing his attraction, Mrs. Leonard--who is cheating on her own husband--urges Bess to take up with Jack. Still feeling ignored by her husband, Bess accepts an invitation to a party at Jack's house, but finds out that things aren't exactly what they seem.
