Evan (Robbie Amell) and Faye (Jordana Brewster) have humanoid A.I.s in their images in their home, just in case anything ever happens to them. When Evan dies in a car crash, Faye has his Simulant activated.

Meanwhile, government agent Kessler (Sam Worthington) is determined to stop the rise of machine consciousness, while A.I. programmer Casey (Simu Liu) works on making the Simulants autonomous beings.
