Based on a novel by the Baroness D'Arville, the independently produced Faithless Lover requires far too many subtitles to tell its story. Handsome engineer Austin Kent (Eugene O'Brien) falls in love with socialite Mary Callendar (Gladys Hullette), who can't see beyond her shallow boyfriend Harry Ayres (Raymond Hackett). Deferring to Mary's wishes, Austin arranges for Harry to be hired by his construction firm, so that the ne'er-do-well youth will be able to afford to get married. Alas, Harry proves to be thoroughly unreliable, capping his many misdeeds by destroying a multi-million-dollar dam project. He also has the nerve to accuse the faithful Mary of fooling around with Austin. Fortunately for the purposes of the plot, Harry is killed in a flood, whereupon Mary realizes belatedly that Austin is the right man for her.
