Sally, a girl of the tenements, is being raised by three bachelor foster-fathers: a pawnbroker, an organ-grinder, and a peddler. She is happy to prepare their meals and keeping the house while the old men bask in the attention she gives them. This happy home is broken up when Sally's wealthy aunt appears and takes her back to her luxurious penthouse to give her the advantages of money and social position. But Sally's heart is back across the river with her plumber sweetheart, Jimmie Adams.
