This film lets loose a considerable number of red herrings. A Parisian cop's wife is having problems losing her memory, or is she? There are Turkish illegal aliens being killed in Paris; is there a serial killer about? Is Jean Reno playing the bad old ex-cop going to betray his young colleague? Is this a French version of Red Riding?
The answers are not what one would expect; though (without giving away anything) it all struck me as a bit pat at the end. But, while the destination felt a bit odd, the journey was great fun.
