Hitting the trail (1918)

Kid Kelly, a gangster in New York's Lower East Side, attempts to rob Goldberg's millinery store. When the police arrive, Flo Haines, who had come to the building to look at an apartment, hides. When the police find her, they charge her with the crime, but the Kid turns himself over to the law instead. After his release, he again meets Flo, who works in an artificial-flower factory by day and at Reverend Roberts' relief mission by night. The Kid soon falls in love with Flo, and his jealous sweetheart Mamie tricks her into coming to her apartment, where she drugs her and turns her over to Joe Carelli, the flower factory's lustful owner. The Kid saves Flo, but when Carelli is found murdered the next day, he is arrested for the crime. The confession of Annie, who had stabbed Carelli in a jealous rage, frees The Kid, who reforms himself and marries Flo.
