is an episode of ''
The Outer Limits '' television series. It first aired on
29 May 1998 , during the fourth season.
Charlie Bouton's last robot design for Innobotics — Valerie 23 — went berserk and attacked its owners. It almost put the company out of business. Now he and his colleague, Melburn Ross, have a new idea: Mary 25 the nanny robot. Naturally enough his bosses are skeptical, that is until Charlie suggests testing the new robot with his own family.
Mary 25 replaces the household's current nanny. She is designed not to allow anyone harm the children - including the children themselves. When they start fighting amongst themselves, Mary places them in separate rooms. Teryl, the mother and Charlie's wife, wants Mary out of the house but Charlie says no since he has started using Mary as a sex toy when the others are asleep. It is then clear that Charlie has been abusing Teryl which becomes clear when the children ask Mary "why does daddy hurt mommy?" It is then revealed that Teryl and Melburn had a relationship once and Melburn still has feelings for Teryl by trying to protect her from Charlie. He then re-programms Mary so that she now considers that by hurting the mother, Charlie is hurting the children. So one night when Charlie is beating up Teryl, Mary comes in and begins to kill Charlie through strangulation, then breaks his neck.
In the aftermath, the first Nanny has been rehired and the spark is rekindled between Teryl and Melburn until Teryl's dark secret is discovered: the real Teryl that Melburn loved was killed by Charlie and was replaced by Valerie 24, the robot that was made after Valerie 23 but was shelved and she used Melburn to help her get rid of Charlie.
