The Nanny [1965][Hammer Horror]

Ten year old Joey Fane has been institutionalized for two years for behavior issues following the "accidental" bathtub drowning death of his younger sister, Susy Fane. Despite those behavior issues not having improved, Joey is being released and is going home. His father, Bill Fane, sees Joey's homecoming as a nuisance as having to deal with Joey's bad behavior takes time away from his work. Joey's mother, Virginia Fane, is a quivering nervous wreck as she doesn't think she can cope with Joey. The only person who seems even remotely happy about Joey coming home is Nanny, a longtime servant who was Virginia and Virginia's sister Pen's nanny when they were children. Nanny still acts much as such to the childlike Virginia and sickly Pen. However, Joey has always hated Nanny, who he wanted and still wants fired. Joey is openly antagonistic to Nanny, he especially refusing to eat anything she cooks and making her swear that she won't come into the bathroom while he's taking his baths. He accuses Nanny of trying to kill him. While at home, Joey befriends precocious fifteen year old Bobbie Medman, the girl who lives upstairs. Bobbie eventually gets caught up in Joey's stories of Nanny.
