Constance, the beautiful wife of Mark Barr, is in fear of her husband's jealousy. Among the guests at their reception are Myrtle Gale and her fiancé, Billy Craig, to whom Constance was at one time engaged. Mark misinterprets a friendly chat between the two and forbids Billy to visit his house. Myrtle goes to the city, and is to return on an early evening train, on which Constance also expects her husband.
