Garment manufacturer Sergius cuts his workers' wages, prompting a protest led by two Russian sisters, Olga and Vera. Sergius's affluent daughters, Hattie and Helen, decide to support the workers' cause, moving into the sisters' tenement and joining the workforce, much to their father's dismay. In a dramatic turn, the daughters bring their work to the factory and confront Sergius. They make a final appeal to him in his office, where he eventually relents and agrees to meet the workers' demands. Following this victory, Hattie and Helen decide to return home to their father, and the good news is shared with all the factory girls, ending the story on a note of general rejoicing.
