Goodnight Mommy

When twin brothers arrive at their mother's country home to discover her face covered in bandages - the result, she explains, of recent cosmetic surgery - they immediately sense that something doesn't add up. She sets strange new house rules, smokes in her bathroom, and secretly rips up a drawing they gave her—things their loving mother would never do. As her behavior grows increasingly bizarre and erratic, a horrifying thought takes root in the boys' minds: The sinking suspicion that the woman beneath the gauze, who's making their food and sleeping in the next room, isn't their mother at all.
