Romantic comedy about a beautiful dizzy blond prostitute who looks a little like Goldie Hawn. She is owned by the mob and wants out, she flees to suburbia and meets a young boy who is smitten with her and brings her home. There is only the boys father at home the mother having passed away. The majority of the movie is about her fitting in at home and with friends, neighbors and the boy's school with many funny and sexy situations along the way. After fitting in comfortably, her and the boy's father fall in love. The ending has her going back to her former apartment after a big fight with the father and retrieving her suitcase which turns out not to be hers but a look-alike full of money from the now dead mobsters. She proceeds to buy the marshland that her new love the father has been trying to save from developers. She shows up to save the day just as the bulldozers move in to fill the marsh. The father relents of his anger of her not telling him she was a former prostitute. They marry and live happily ever after.

Sounds like it could be Milk Money.
