The scoop: The directors of Goodnight Mommy are back with another horror movie, so I hope you're not too attached to the idea of ever sleeping again. In Veronika Franz and Severin Fiala's latest, soon-to-be stepmom Grace (Riley Keough) finds herself snowed in at her fiancé's (Richard Armitage) remote Winter vacation home with his two young children. After their father leaves, the kids do some digging into Grace and discover that she's the sole survivor of a creepy cult's mass suicide years earlier. That's when all hell breaks loose.
