What begins as a quiet evening for the Thompson children quickly spirals into a waking nightmare in this tense psychological thriller. When their regular babysitter cancels, parents Dan and Joyce hire Anna, a seemingly perfect replacement recommended by a friend. As played by Sarah Bolger, Anna, who soon asks the kids to call her Emelie, initially charms the children with her playful and permissive attitude. However, her behavior grows increasingly strange and unsettling as the night progresses, revealing a deeply disturbed individual with a hidden agenda. The eldest son, Jacob, begins to sense that something is terribly wrong with the woman in charge, but his younger siblings remain under her manipulative spell. Directed by Michael Thelin, the film masterfully builds an atmosphere of creeping dread within the familiar confines of a suburban home, transforming ordinary objects and childhood games into sources of profound unease. As Emelie’s true intentions come to light, the children must find a way to see through her deceptions and survive a night with a stranger who is nothing like she appears.
