Rings on Her Fingers(1942)

Susan Miller works behind the girdle counter in a department store and dreams about the beautiful clothes and glamour she can never hope to have. Enter May Worthington and Warren, a pair of con artists who pose as the mother and uncle of a pretty girl in order to separate millionaires from their money. They convince Susan she has an opportunity to fulfill all her dreams, and the trio heads for Palm Beach. Susan meets John Wheeler who says he is shopping for a sailboat. Believing that he is a millionaire, Warren and May sell him a boat that doesn't belong to them, and make off with his $15,000 life savings. Looking for greener pastures, they work themselves into the family of wealthy Tod Fenwick, who falls for Sue, posing as "Linda Worthington". But John shows up as a guest of Fenwick and he tells "Linda", not knowing she was part of the scam, that he has a detective after the fake captain that sold him the boat...
