Marion Shipley is happily devoted to her husband, John, until Mrs. Willy Strong, a society "vampire," succeeds in capturing his affections. A jewelry salesman informs Marion of the affair, after John and Mrs. Strong enter his store together. Marion follows her husband to a restaurant, where she witnesses Mrs. Strong give John the key to her apartment. Gaining entrance to her rival's home, Marion transforms herself with the vamp's clothes and makeup, rendering herself unrecognizable to John in the dim light. Marion is in John's arms when Mrs. Strong arrives, and he denounces her for his wife.
