Esmeralda Marini (Claudia Cardinale) arrives in New York to visit family friend and her father's friend Mike Harmon (Rock Hudson). He hasn't seen her since she was much younger. He is a strict by-the-book Police Captain. She is a flighty rebel and reveals that she's in possession of stolen jewels from the wealthy Fairchilds. Her criminal partner is the infamous thief Jackie Mitchell. Mike promises to help her return the jewels.
There must be a better way to do this. He's a cop. There must be some low life's home where he could claim to have found the jewels. The fact is that neither character would do this that they are proposing. They are both obviously lying and both should obviously know it. The other problem may be cultural. This is an Italian film and the young hot girl is obviously going to sleep with the older man. It doesn't help that he knew her when she was a child. There has to be a convoluted situation where she strip down to her underwear and gets sprayed on. All in all, this rubs me the wrong way and then the story is pretty dumb in the first place.
