"You deserve someone to show you mercy. From the creator of American Horror Story, witness the origin of one of the world's most iconic characters, Nurse Ratched," Netflix adds on the trailer upload.

The streamer's full description reads as follows: "In 1947, Mildred arrives in Northern California to seek employment at a leading psychiatric hospital where new and unsettling experiments have begun on the human mind.

"On a clandestine mission, Mildred presents herself as the perfect image of what a dedicated nurse should be, but the wheels are always turning and as she begins to infiltrate the mental health care system and those within it, Mildred’s stylish exterior belies a growing darkness that has long been smoldering within, revealing that true monsters are made, not born."
