The Turning

A young woman, Kate Mandell (Mackenzie Davis), quits her teaching job to become a governess for two wealthy young children, Flora (Brooklynn Prince) and Miles (Finn Wolfhard), after their parents' death. She soon starts to suspect there's more to their house, the Fairchild Estate, than meets the eye, and as she delves deeper, she uncovers a dark history of obsession, possession, and descent into madness.
