This is a very entertaining, icy film about two women in a Paris corporate environment who have a fatalistic relationship. I won't say much more but the twist comes on very early and it's a lot of fun seeing it unravel. At times it got a bit unbelievable and occasionally it is just too ice-cold, robotic and hard edged to really have any feeling for, but it was this mercilessly calculating side to it which I enjoyed, as you don't see it often in films.
