The Innocents (1961)

Miss Giddens applies for a job as a governess. It is to be her first position, but the wealthy bachelor interviewing her is unconcerned with her lack of experience. He values his freedom to travel and socialise and unabashedly confesses that he has "no room, mentally or emotionally" for his niece and nephew. They were orphaned and left in his care as infants, and he keeps them at Bly, his large country estate. The previous governess, Mary Jessel, died suddenly less than a year ago. All he cares about is that Miss Giddens accept full responsibility for the children, never troubling him with whatever problems may arise.
