Two masked cops go after some drug dealers and steal their drugs. One of them, Vincent, is injured in the ensuing fight. He's also identified by one of the criminals and witnesses. As a result, the big bad drug lord, Jose, kidnaps Vincent's son to get his drugs back. Now Vincent forcefully explains to his partner Manuel, that he needs the drugs while Manuel wants his cut and needs the money. Later Manuel meets with a crooked internal affairs cop.
Vincent retrieves the drugs and goes to Jose's lair, a giant dance club/restaurant/bar/private club for perverts and more. But he was followed by a female IA. She sees him go in the men's restroom with a bag but exit without the bag. So she goes in the men's restroom and finds the bag in the ceiling. She takes it and hides it in the women's restroom ceiling.
Vincent with just one little packet of drugs meets Jose and demands to see his son. After Jose checks the drugs and Vincent sees his son he offers to return in a few minutes with the rest of the drugs, which of course aren't there anymore. So he devises a plan and goes to the kitchen and gets the staff to fill packets with flour and put them in a bag. But by now another foreign gang has arrived demanding the drugs from Jose. The ruse works and Vincent gets his son back, but only for a while. He quickly loses his son again to the thugs.
Now with no more moves to make he has to get his son back, with Jose and his henchmen after him as well as the two IA agents and Vincent's ex-wife constantly calling him on the phone.
Nuit Blanche is quite thrilling at first. Everything up to the point where he loses his son after getting him is very exciting, timing is very important for Vincent and we are on the edge counting the seconds till the foreign drug dealers discover the ruse. Things slow down then for a bit as Vincent has no way out--no drugs, no weapon (he hid his somewhere in the club). But quickly things pick up again as he confronts the IA agents very violently and things get a little funny too as he uses some cute girl he rescued earlier from a pushy guy to hide and escape from all the people after him. Story-wise too there are several twists and turns and things aren't quite as they seem.
But, too much time is spent on the son, the ex-wife, kitchen fight scenes. Vincent running through a very crowded club gets repetitive fast. Almost the entire movie is set in the club and despite attempts to give us a variety of environments, it does get tiring after a while. Nevertheless, for a Heat-inspired French action thriller, this movie is worth watching.
