After the underlying tech for M3GAN is stolen and misused by a powerful defense contractor to create a military-grade weapon known as Amelia, M3GAN's creator Gemma realizes that the only option is to resurrect M3GAN and give her a few upgrades, making her faster, stronger, and more lethal.

A brilliant toy company roboticist uses artificial intelligence to develop M3GAN, a life-like doll programmed to emotionally bond with her newly orphaned niece. But when the doll's programming works too well, she becomes overprotective of her new friend with terrifying results.

One year since the supernatural nightmare at Freddy Fazbear's Pizza, the stories about what transpired there have been twisted into a campy local legend, inspiring the town's first ever Fazfest.

But an unholy night of horror awaits as Annabelle awakens the evil spirits in the room, who all set their sights on a new target—the Warrens' ten-year-old daughter, Judy, and her friends.
