Miss Grant Takes Richmond(1949)

She was never so insulted in all her life...and it was wonderful!

A bookie uses a phony real estate business as a front for his betting parlor. To further keep up the sham, he hires dim-witted Ellen Grant as his secretary figuring she won't suspect any criminal goings-on. When Ellen learns of some friends who are about to lose their homes, she unwittingly drafts her boss into developing a new low-cost housing development.
