This picture opens on the big, helpless humanity which is huddled together in Blossom Street, in the East Side's slums. The sweetest spirit of the thousands dwelling there is Anne, in love with Jimmy Graves, a man she knows is a crook. In warning Jimmy one night that the police are on his trail, she is caught in the maelstrom, brought into court with him and sentenced to jail. When she is released she plots revenge on the man who put her behind the bars, Judge Marcus, about to be nominated for a higher position in public service. Through a ruse, she obtains employment in the Marcus household. The Judge does not recognize in his wife's secretary the same woman who was once just a "poor, Blossom Street thing." He finds that he is rapidly falling in love with her. Anne is approached by a stool pigeon working for Marcus's political opponents, who are trying to fasten a scandal upon the Judge. Anne promises to aid them. She agrees to put him in a compromising position that evening, when witnesses will be on hand. Meantime, Jimmy Graves is released. He has been living through the years of his prison term, with the face of Anne always before him. He learns that the girl is at the Marcus home, and starts for the house. As the hour for the denouement draws near, Anne realizes she loves Marcus. He kisses her again and again. She notices the clock and pushes him from her just before the curtains are thrust back by the politicians and Mrs. Marcus. Jimmy arrives, and in the face of her love for Marcus, she sacrifices herself that the judge may win.
