Moral Suicide (1918)

Wealthy Richard Covington, although aging and lonely, distresses his children, Waverly and Beatrice, by marrying a heartless seductress named Fay Hope. Because Fay's extravagant spending threatens to ruin Richard, Beatrice confronts her, which prompts Richard, who is hopelessly in love with the beautiful vampire, to order his daughter from the house. Fay introduces her lover, "Lucky" Travers, into the Covington household as her brother, but Waverly catches them in each other's arms and, in a fit of insanity, shoots at Lucky. The bullet strikes and kills Fay, and Waverly is locked in an asylum, leaving Richard broken, penniless and completely alone. In New York, he finds work carrying sandwich boards that advertise a cabaret, where he sees Beatrice warmly conversing with Lucky. Beatrice consoles her distraught father by admitting that she now works for the Secret Service. After securing Lucky's arrest, Beatrice returns to her fiance, Rodman Daniels, who has arranged Waverly's release from the asylum, and the entire family is reunited.
