Two years after M3GAN, a marvel of artificial intelligence, went rogue and embarked on a murderous rampage and was subsequently destroyed, M3GAN’s creator Gemma (Allison Williams) has become a high-profile author and advocate for government oversight of A.I. Meanwhile, Gemma’s niece Cady (Violet McGraw), now 14, has become a teenager, rebelling against Gemma’s overprotective rules. Unbeknownst to them, the underlying tech for M3GAN has been stolen and misused by a powerful defense contractor to create a military-grade weapon known as Amelia (Ivanna Sakhno from Ahsoka, Pacific Rim: Uprising), the ultimate killer infiltration spy. But as Amelia’s self-awareness increases, she becomes decidedly less interested in taking orders from humans. Or in keeping them around.

With the future of human existence on the line, Gemma realizes that the only option is to resurrect M3GAN (Amie Donald, voiced by Jenna Davis) and give her a few upgrades, making her faster, stronger, and more lethal. As their paths collide, the original A.I bitch is about to meet her match.

Directed by Gerard Johnstone, the film co-stars returning cast members Brian Jordan Alvarez and Jen Van Epps as Gemma’s loyal tech teammates, Cole and Tess, and new characters played by Aristotle Athari (Saturday Night Live, Hacks), Timm Sharp (Apples Never Fall, Percy Jackson and the Olympians) and Grammy winner and 11-time Emmy nominee Jemaine Clement (Avatar: The Way of Water, What We Do in the Shadows).

Produced by James Wan, Jason Blum and Allison Williams, the film is executive produced by Gerard Johnstone, Adam Hendricks, Greg Gilreath, Michael Clear, Judson Scott and Mark D. Katchur.
