Simon (Kacey Mottet Klein) is a thief stealing from the foreigners at the ski resort. He lives with his aimless irresponsible sister Louise (Léa Seydoux). She's left yet another job and has questionable relationships. He gets caught by resort worker Mike (Martin Compston) but instead he starts selling the stolen skis to him. He takes bigger and bigger risks. He's an expert liar. He befriends resort patron Kristin Jansen (Gillian Anderson) pretending to be a rich kid.
It's a pretty good performance from Kacey of a ballsy character. It does need to amp up the danger for the boy. While the reveal is great, it doesn't really raise the danger. Maybe if they could add a thug looking for money or children services looking to take Simon away. Also it would be great to dig deeper into Louise's problems. Overall this is a little bit disturbing but needs to raise the tension much higher.
