Two years have passed since the bloody massacre caused by the legendary M3GAN. After creating the killer doll, Gemma (Allison Williams) became a renowned developer and is now fighting for control over AI. Her niece, Cady (Violet McGraw), has grown into a rebellious teenager.
Meanwhile, a powerful military corporation, using M3GAN's core technology, has developed a new superweapon — Amelia (Ivanna Sakhno). She's fast, smart, and has no intention of following human orders. Now, to save the world, Gemma must bring M3GAN back… But this time, she has to be even stronger, even more dangerous, and even crazier.
The original team, led by James Wan and Jason Blum, is preparing an incredible blend of action and horror! Director Gerard Johnstone returns, and new faces join the cast, including Ivanna Sakhno and Jemaine Clement.
