Kathy is a nice, pretty, single, dependable working girl. She's always helping others, caring for her recently widowed father and tends to be at the beck and call of her married, younger, unappreciative . sister.
As a thank you gift, she is given a ticket to a charity luncheon. She hesitantly decides to attend the event and meets several women. When Kathy says she works at "The Market", the ladies assume that she is a stockbroker (she is a grocery clerk) and the movie takes off.
Not being a stuffy society woman, "Kathryn" catches the eye of wealthy, handsome, Grant Sherwood. Romance begins and "Kathryn" continues the charade while also living Kathy's life.
Mix into the plot some jealously, soul searching, Kathy's newfound assertiveness, plus a secret that Grant has of his own and you have a pretty nice movie.
