At the UN today, the French representative didn't show though few made much notice of it. However, a French reporter is given the assignment to look for the guy and see why he disappeared. To help, he gets the help of a super-sleazy photographer, Pierre, and the pair bounce about New York following leads. They think this well respected man might have a mistress--and several photos of him with ladies might help them locate the guy.
Eventually they locate the man and then comes an important decision- -what to do with this information. The photographer, naturally, wants to make the most of it and spread sensationalistic photos everywhere. The other guy is decent and tries to get his new partner to do the right thing.
I love the films of Jean-Pierre Melville--at least up until this one. It's not a terrible film but nothing like the great film noir features Melville made (mostly in the 60s and 70s). But it did have a homemade feel--cheap and definitely more French New Wave than his usual more polished work. Lots of cheap stock footage of New York was used and so many of the English-speaking actors sounded anything but like New Yorkers. French audiences probably wouldn't have recognized this, but to an American the accents often don't fit or sometimes sound like foreigners TRYING to sound American...and failing. Mildly interesting and clearly the last portion is by far the most interesting. Plus, being a French film it has some nudity, lesbianism and other plot elements you just wouldn't have found in an American film of the time.
