Ringwald is a young woman whose father's in trouble with the mob (gambling debts), and she needs money to help him. Downey is the title character, a guy who never strikes out with women. Need I tell you that Ringwald burns him? And that they'll get together eventually?
This is a messy movie. It has a great cast going for it (besides the two main characters, there are Dennis Hopper, Harvey Keitel, Danny Aiello, Vanessa Williams, Robert Towne [yes, the Chinatown guy], and Lorraine Bracco in one of her first U. S. movies). There are a few amusing moments. The cast and those moments can't save the movie, though. It remains, for me, an oddity from the '80s.
