Every now and again you come across a film that you know very little about but fine the premise intriguing and it more than lives up to that intrigue. Juliette Binoche - who is in pretty much every scene - is a mesmerising presence as Claire - a lonely university professor who is struggling with inner demons. To say anything else would spoil. Suffice to say, this is a film which, whilst easy to follow and you never know what's going to happen next, would no doubt benefit from a second viewing. I will definitely be watching again. Currently streaming on Netflix - this is a sexy, twisty drama/thriller that at least for me was a hidden gem. 8.5 out of ten
