Ils – aka Them

A French teacher, Clementine (Olivia Bonamy), and her husband, Lucas (Michael Cohen), living in a rural house in Romania. One day on her way home she sees a vehicle abandoned by the side of the road. What she doesn't know is that the car's occupants, a mother and daughter, were killed the night before by unseen intruders. That night, the intruders being working on Clementine and Lucas. First it's just prank phone calls and mind games, but as the torment escalates, the couple have fewer and fewer places to turn for safety. Adding to the terror, it's not at all clear whether the intruders are human or something else.
