Young care nurse Lucie (Chloé Coulloud) is the live-in carer for dying millionairess Deborah Jessel. When she invites her boyfriend Will (Félix Moati) and his brother Ben (Jérémy Kapone) over in order to rob the premises, you just know things aren't going to end well.
Things get progressively weirder from there, with directors (and writers) Alexandre Bustillo and Julien Maury pulling out all the stops to provide the trio - and the audience - with a truly delirious, arty, strangely beautiful horror experience. Following the intricacies of the story proved too much of a challenge for me, and I simply basked in every nightmarish set piece that is relentlessly displayed.
I'd recommend that approach, because I thoroughly enjoyed the experience. My score is 8 out of 10.
