Anyone help me name this movie please...I'll give props.

I've seen this movie years back and I would like to see it again but I forgot the title.I hope the summary I put down helps, my memory's a little foggy since it's been quite a while since I've seen the movie.

A lady met this Frenchmen on a train, he previously चुरा लिया some expensive jewelry and hid it in her bag. When she got of the train in Paris, she took the bag that had the jewelry he stashed in it. In an attempt to get it back without being to conspicuous he follows her around Paris to try to get the jewelry back. Along the way they run into और trouble and then they realize they aren't enemy's and a little और than just friends.

Thank You!!!!!!!
