The Hand That Rocks the Cradle (1992) on Netflix

Dr. Victor Mott is a respected and successful gynecologist, but his respect and success both come to a crashing halt when he is accused of sexually molesting his patients. When Claire Bartel accuses him of this crime, four other women come forward to corroborate the story and also accuse the doctor. Stripped of his license and on the verge of being sent to prison, Dr. Mott commits suicide. As if this were not enough of a blow to Dr. Mott's now-widowed wife, she suffers a miscarriage, losing her unborn baby as well, and is on the verge of losing her home to civil judgments against her husband's estate. Broken, alone and now near-penniless to boot, Mrs. Mott learns that Claire is seeking a nanny for her own young children, and sees this as the perfect tool to exact a bloody revenge on Claire Bartel, and take Claire's family for her own...
