The Nut (1921)

Charlie Jackson, a Greenwich Village bachelor, is in love with his neighbor, Estrell Wynn, who has a theory that poor children can be made into proper citizens by being exposed periodically to homes of the wealthy. To aid her theory, he entertains rich patrons, but they leave in indignation at a premature fireworks explosion. After a number of wild adventures, Charlie rescues Estrell from rival Philip Feeney, and, with the aid of millionaire cub reporter Pernelius Vanderbrook, Jr., they are married.
