Young Celeste Janvier ( Bessie Love ) lives in an East Side tenement with her immigrant grandfather, a humanitarian and socialist. Like her kindly grandfather, Celeste also has a kindhearted soul, and her friendly nature has earned her the nickname, " the little sister of everybody." When several unpleasant men try to court her, Celeste turns them down. Meanwhile, Hugh Tavers Jr., ( George Fisher ) whose father owns a factory, has died suddenly. The young Tavers poses as a laborer in order to understand why the workers want to strike. He meets and falls in love with Celeste, who works at the factory, and he secures a better job for her. Celeste learns that anarchist Ivan Marask ( Hector Sarno ) plans to kill Travers, she hurries to warn her employer and is shocked to learn that he is the poor laborer whom she loves. Marask comes to respect Travers, who agrees to improve working conditions for the factory workers, and finds lasting contentment with the lovely Celeste.
