Desc: The Power of Evil: Directed by E.D. Horkheimer, H.M. Horkheimer. With Henry King, Marguerite Nichols, Lillian West, Frank Erlanger. Stuart Merwin, who is heir to the Stuart millions, loves Laurine Manners, who has been introduced to society at the home of Mrs. Willie Clowes, a widow of decidedly energetic temperament. Tommy Carter, a sprig of society, is also in love with Laurine. Merwin's father has been, during his lifetime, a confirmed alcoholic, and the taint of his dissipated habits is bred in the bone of his son. At Mrs. Clowes' party, Merwin, urged by the hereditary craving for strong liquor, overindulges. He becomes helpless, and in that condition is seen by Laurine, who is disgusted with him. After leaving Mrs. Clowes' home in disgrace, Merwin enters a disreputable resort, known as "Harry Slavin's." He has hardly seated himself at a table before Jeano, a woman of the streets and a habitué of Slavin's, becomes involved in a fight with her paramour, "Slick Mike," a crook. Merwin's decent instincts are aroused and he springs from the table. He fells the bully, but the effort is too much for his befuddled mind, and he crumples to the floor in a senseless heap, but Jeano senses that in the sordid wreck who lies before her there is the germ of better things. Inspired by the fact that he has interfered in her behalf, Jeano takes Merwin to her home, and constantly urges him to build up a new life. Merwin obtains employment in a humble occupation, but with the courage of a new birth in his soul, he endures the toil. In the meantime, Laurine has become a member of the fast set. Mrs. Clowes, herself a woman who regards society as being her lawful prey, urges Laurine on to a desperate flirtation with Tommy Carter. Seeing that Merwin has reformed, Laurine renews her determination to marry the young millionaire, and under Mrs. Clowes' guidance she succeeds. Although he is married to Laurine, Merwin's heart still reverts to Jeano. Soon after their marriage Laurine seeks her old friends and Merwin finds himself neglected. Heartbroken, he reverts to the old life. He again visits Slavin's resort and becomes a broken down wreck. Jeano, who has adopted the uplift work of the Salvation Army, is horrified one night when on entering Slavin's place she stumbles across the out-sprawled form of the man she loves. On the same night, Laurine and her fashionable friends have planned a slumming party, and after imbibing numerous quarts of champagne, they decide to visit Slavin's place. Laurine has scarcely stepped across the threshold when she comes face to face with Jeano who is ministering to Merwin. As the women face each other, Laurine sees in Merwin's face his adoration for the girl who attempted to work his redemption. On her knees, Laurine begs Merwin's forgiveness. Merwin, his better instincts aroused, takes Jeano by the hand and they leave the sordid hovel to begin anew together.
