Unable to keep a job for more than a few days because of her bosses' unwanted romantic advances, beautiful and feisty Ninetta decides to take matters into her own hands. Fed up with the current situation, Ninetta slips into a fashionable suit, dons a wig, and summons up the courage to pose as a man to get a job and earn a living. That should do the trick, and from now on, no one will bother her. However, what happens if Ninetta finds love in her new office?
