It could be a mix of DJINNS and PICNIC AT HANGING ROCK. It also could be influenced by all those horror military outpost stories that were shown several years ago, and which even continue now. Tales involving lost platoons in the middle of nowhere, in the desert or all kinds of wilderness, lost patrol who had to fight against an invisible unknown evil. This feature is very realistic and carried by a solid acting too. Characters are convincing. But no gore sequences here. And I will also emphasize on the eerie atmosphere, weird, especially the scene where the group of soldiers try to catch the evil spirit who abducted some of their men...Their fellow comrades. Jérémie Rénier plays here the chief of those men. Remember, he also played a soldier in LE GRAND HOMME, last year.
Worth watching.
