Ah. Not a bad movie.
Cher's character is engaged to be married to a wealthy businessman who she isn't that attracted to, but the money impressed her parents. Her fiancé asks her to tell his little brother with whom he is estranged that he's getting married. So Cher finds little bro (played by Nicholas Cage), and sparks fly. They see an opera together and enjoy all the finer things in life for a single night.
The next morning after sleeping together, Cage tells Cher he's in love with her. She slaps him twice REALLY hard and yells at him, "Snap out of it!!" LOL classic part and very funny.
Personally, I liked Olympia Dukakis better than anyone in the movie. But it's overall pretty good.
