A roboticist working on a life-like toy android named M3GAN takes in her orphaned niece. She pairs the two up, trying to solve for both issues...and it does not go as planned.

From James Wan, the producer of Annabelle, and Blumhouse, the producer of The Black Phone, comes a fresh new face in terror. M3GAN is a marvel of artificial intelligence, a lifelike doll that's programmed to be a child's greatest companion and a parent's greatest ally.

Designed by Gemma (Allison Williams, Get Out), a brilliant roboticist, M3GAN can listen, watch, and learn as it plays the role of friend, teacher, playmate, and protector. When Gemma becomes the unexpected caretaker of her 8-year-old niece, she decides to pair the girl with a M3GAN prototype, a decision that leads to unimaginable consequences.
