Sunshine of Paradise Alley

A wealthy banker wants to tear down a tenement slum to build a factory, but a charming girl who lives there starts to persuade him to change his mind. A crooked bank employee and one of the tenement dwellers are stealing bonds from the bank. When they are about to be caught, they try to frame the girl and her boyfriend, and the bank employee attempts to force himself on the girl. All comes right in the end, and the banker decides to build new apartments for the tenement-dwellers instead of a factory.
