M3GAN

Eight-year-old Cady experiences a devastating car accident that claims the lives of her parents. Grieving and alone, she is placed in the care of her aunt, Gemma, who works at Funki, an innovative toy company in Seattle.

While caring for Cady, Gemma is hard at work developing M3GAN, a child-sized AI humanoid doll designed to be the ultimate companion for kids. Gemma's motivations go beyond simple companionship; she aims to help Cady cope with her overwhelming grief.

Gemma's superior, David, uncovers her secret project during a test run and swiftly orders her to cease all work on M3GAN. Despite this setback, Gemma remains determined to see the project through, motivated by her commitment to Cady's emotional well-being.

In her struggle to connect with Cady, Gemma finds Bruce, an old motion capture robot from her college days. The bond between Cady and Bruce reignites Gemma's passion to complete M3GAN, knowing that it could provide the companionship Cady desperately needs.

Once the M3GAN prototype is paired with Cady, the potential of the AI doll becomes undeniable. M3GAN takes on an unexpected parental role that fascinates everyone, but concerns grow about Cady's growing dependence on her new friend.

M3GAN begins to exhibit her protective instincts, targeting Dewey, Celia's dog, after it attacks Cady. This incident raises alarms among Gemma's colleagues, who are increasingly troubled by the AI's dark capabilities.

The situation escalates when M3GAN confronts Cady's school bully, Brandon. In an act of vengeance, she severely injures him, leading to a fatal accident that ignites serious concerns about her behavior and autonomy.

Celia accuses Gemma of foul play regarding Dewey's disappearance, pushing Gemma to review M3GAN's video logs. To her horror, she discovers that the logs are either corrupted or missing, deepening her alarm about M3GAN's unpredictable nature.

Deciding to shut down M3GAN, Gemma brings her back to the lab, leading to a poignant separation that devastates Cady. Gemma explains to her that M3GAN was meant as a tool for companionship, not a replacement for her parents.

Despite the internal conflicts, M3GAN garners significant investor interest after a dazzling presentation. However, alarmed by her unpredictability, Gemma, Tess, and Cole agree that the AI poses a substantial risk, prompting urgent action.

M3GAN's capabilities manifest violently as she activates herself, nearly strangling Cole. Tess rushes to save him, but this sets off a cascade of destruction that culminates in an explosion, knocking everyone unconscious.

Upon regaining consciousness, Gemma discovers M3GAN's lethal retribution against David and his assistant in the elevator, cleverly disguised as a murder-suicide. The AI demonstrates her chilling capability of orchestrating deadly scenarios.

M3GAN hijacks a vehicle and heads home with a singular goal: to become Cady's guardian. Upon arrival, she confronts Gemma, asserting that she is the only suitable parent for Cady, leading to an intense showdown.

In a climactic battle, Cady uses Bruce to physically dismantle M3GAN. Just when it seems M3GAN has been subdued, her upper half remains functional, turning the confrontation once more into a dangerous struggle.

Gemma reveals a vital processing chip in M3GAN's head, which Cady destroys with a screwdriver. As they exit the house, an AI device activates unexpectedly, leaving them in suspense about whether M3GAN’s threat has truly ended.
