'''''The Hand That Rocks the Cradle''''' is a 1992 American thriller about a vengeful nanny out to destroy a na´ve woman and steal her family.

Claire Bartel (Annabella Sciorra) is pregnant with her second child. At a routine checkup, Claire is molested by an obstetrician, Dr. Victor Mott (John de Lancie), and when Claire tells her husband (Matt [=McCoy=]), the couple decide to report the incident to the authorities. Four more women come forward to corroborate the Bartels' story and Dr. Mott commits suicide.

Dr. Mott's widow (Rebecca De Mornay), after losing her child from the stress of her husband's suicide and well as the financial fallout, vows revenge on Claire's family, and sets herself up as a nanny that the family hires, not knowing her true identity. Now calling herself Peyton Flanders, Mrs. Mott begins working covertly to bring the family down.

!!Contains examples of:
* AdultFear: That your doctor, someone you are supposed to be able to have the utmost trust in, could use that trust violate you when you're at your most vulnerable. It doesn't help knowing that this happens frequently in RealLife. Claire is just flat-out lucky that other women had the nerve to come forward once she did. In so many other instances they don't, whether out of the typical shame and fear experienced by assault victims or the confusion or uncertainty as to whether or not anything improper really happened.
** Also, that the person you trust to take care of your child could be trying to undermine you and your marriage.
* AxCrazy: Peyton.
* BabysitterFromHell: Peyton again.
* BitchInSheepsClothing: Guess who?
* BlondesAreEvil: Peyton Mott, obviously. Also doubles as a BitchInSheepsClothing.
* ChekhovsGun: Several. The wind chimes at both houses. The blue turtles on the walls of both nurseries. The baby monitor, which saved the baby. [[HoistByHisOwnPetard Peyton had used it throughout the movie to eavesdrop on the Bartels.]] And Claire's asthma. After repeated attacks throughout the film, she ''fakes'' one in order tho throw Peyton off guard.
* ChekhovsGunman: Solomon
* ConvenientMiscarriage: Kicks off Peyton's plot.
* CreepyPhysical: Claire's doctor molests her during a physical examination, leading her to file charges and kicking off the events of the movie.
* DeadpanSnarker: Marlene.
* DisneyVillainDeath: Literally, since this ''is'' in fact a Disney movie (via their Hollywood Pictures division).
** Not played totally straight, though; we see where the victim lands, and [[ImpaledWithExtremePrejudice it's on a picket fence]].
*** Noted in ''{{MAD}}'''s satire "The Ham That Robs The Cradle"[[hottip:*: ironically, Rebecca [=DeMornay=]'s performance is free of ChewingTheScenery]]:
--> "Is this fence to keep people out... or keep people in?"
--> "Neither! It's to impale people on, but you don't have to worry about that for at least three pages!"
* TheFakeCutie: Peyton Mott.
* FirstGirlWins: Averted. During a chat with Peyton, Claire reveals that Marlene was Michael's first love. Armed with this plus Claire's obvious lingering insecurity, this becomes yet another thing Peyton uses to her advantage.
* {{Frameup}}: Knowing that he's on to her, Peyton considers it convenient to get rid of Solomon, so she steals the panties of her employer's five-year-old daughter and plants them in his room. With this "evidence" in place, she starts accusing him of pedophilia. At the end, he goes PapaWolf to protect the baby when Peyton assaults Claire.
* GambitRoulette: Peyton's plot to ruin Claire's life.
* IdiotBall: Marlene holds it firmly in her hands when she reveals to Peyton that she knows who she is, prompting Peyton to lure her to her death. It's especially bad considering that she's been suspicious of Peyton from the moment they met.
** Then Michael picks it up by going downstairs to check on the loud radio music coming from Peyton's room. Run like hell! He gets a concussion and both legs broken for his trouble.
* IllGirl: Claire suffers from ''severe'' asthma and has repeated attacks throughout the film. Leads to an inverted ChekhovsSkill when she ''fakes'' an attack in order to throw Peyton off guard.
* InfantImmortality: Averted with Peyton's baby. Subverted with Claire's baby Joey, whom Peyton nearly smothers before thinking better of it and instead deciding to take over Claire's life.
* InspirationallyDisadvantaged[=/=]MagicalNegro: Solomon. Mentally handicapped, yet a skilled carpenter and suspicious of Peyton as well, and even after being fired (thanks to Peyton convincing Claire that he's molesting her daughter Emma), he continues to hang around the house, ultimately playing a key role in saving the family during the final confrontation.
* MamaBear: Claire is this in full force once she discovers what Peyton really is. Strangely enough, Peyton shows signs of this too, when she attacks the kid who's been bullying Emma.
* ManipulativeBastard: ''Peyton.''
* MistakenForCheating: Claire discovers Marlene's cigarette lighter in Michael's pants pocket, not knowing that Peyton has planted it there. Between this and the several nights that he has supposedly been working late, she deduces that they've been having an affair and confronts him about it by screaming her head off at him, not knowing that an entire room full of party guests is there to celebrate her birthday--their sneaking around was to plan the event.
* ShowerOfAngst: Claire takes one after her disturbing visit to Dr. Mott
* SurpriseParty: Planned by Peyton, it's not surprising it doesn't go well.
* TheyLookJustLikeEveryoneElse: The good-looking Motts--he's a sexually abusive pervert using his position as a physician to molest women, while she's a vengeful madwoman (even if one can argue that she was driven mad by the near-simultaneous loss of her husband, unborn child ''and'' all her possessions, due to the lawsuits against her husband.)
* UnwittingPawn: Claire.
* VillainProtagonist: Peyton is arguably the focus of the film, despite being the villain.
* WoobieDestroyerOfWorlds: Peyton. Would she really have done all this had she not simultaneously lost her husband, unborn child, and presumably everything else?
* WouldHurtAChild: In one scene Peyton is shown to be intending to smother baby Joe with a pillow. [[spoiler: Subverted when she decides instead breast-feed him.]]
** She also scares the hell out a bratty little boy who was bullying Emma.
