Upgrade

In 2046, Grey Trace, an auto mechanic, lives with his wife Asha who works for Cobalt, one of the companies contributing to human-computer augmentations. Grey asks Asha to help him return a refurbished car to his client Eron Keen, a renowned tech innovator. While visiting his home, Eron reveals his latest creation, a chip called STEM that can manage a human’s motor functions.

Returning home, Grey and Asha's self-driving car malfunctions and crashes. Four men kill Asha and shoot Grey in the neck, severing his spinal cord. Grey returns home months later as a wheelchair-using quadriplegic, under the care of his mother, Pamela. Asha's death and the inability of Det. Cortez to identify their attackers causes Grey to sink into depression. After a suicide attempt, he is visited by Eron, who convinces him to accept a STEM implant.

Grey regains control of his limbs and Eron has Grey sign a non-disclosure agreement, requiring Grey to pretend to still be paralyzed. While looking through a drone video feed of his wife's murder, Grey hears STEM speak in his mind. STEM says it can help Grey get revenge and quickly identifies one of the assailants, Serk Brantner, from the video.

Grey breaks into Serk's home and finds proof Serk was "upgraded" through a secret military experiment, also connecting Serk to a local bar called the Old Bones. Serk arrives and attacks Grey, but STEM convinces Grey to temporarily give up control of his body, allowing STEM to turn Grey into a lethally efficient fighting machine, killing Serk with little effort. Cortez later sees drone footage of Grey’s wheelchair approaching Serk’s house, but his perceived paralysis negates him as a suspect.

Eron has tracked STEM's movements and berates Grey for his vigilantism. Grey reveals STEM is speaking to him, which surprises Eron, who demands that Grey stop his investigation.

Grey proceeds to the Old Bones and finds Tolan, another of the assailants. Grey allows STEM to torture Tolan to death, first getting the name of the assailants' ringleader, Fisk. Leaving the bar, Grey stumbles, and STEM informs him that Eron is attempting to shut them down remotely. STEM directs Grey to a nearby hacker, Jamie, who manages to remove STEM's input guard, then leaves just as Fisk arrives. Grey, with STEM's control restored, kills Fisk's companion.

Grey returns home only for Pamela to see him walking, forcing him to reveal STEM's existence. Cortez arrives to interrogate them after finding Grey's wheelchair suspiciously abandoned at the Old Bones; she leaves after planting a listening device on Grey's jacket. Grey wishes to give up the hunt, but STEM explains that Fisk will track them down and kill them. STEM reveals that the hack gives it free control of Grey’s body. STEM uses Grey to drive to Fisk, causing an automated car to malfunction and crash into Cortez, who is tailing them. Cortez returns to Grey's home, where Pamela explains STEM.

Grey and STEM find Fisk, who reveals he was only hired to paralyze Grey so he could be implanted. Fisk's own upgrades outpace Grey's movements. Grey taunts Fisk with the death of Serk, his brother, allowing STEM to gain the upper hand and kill Fisk. Fisk's phone reveals messages from Eron, suggesting he orchestrated all the events.

Grey storms Eron's home, killing all personnel in his path, but is held at gunpoint by Cortez before he can kill Eron. Eron confesses how STEM forced him to do its bidding, having long since come to dominate all aspects of Eron's life in pursuit of its goal to become human. STEM kills Eron and attempts to kill Cortez, but Grey fights for control over his own body, managing to stab himself in the hand.

Grey wakes up in a hospital room, not paralyzed. Asha explains he has been unconscious for two days following their crash. In reality, Grey is still in Eron's home. STEM, in full control, explains to Cortez that the psychological strain has finally broken Grey's mind; this was STEM's objective all along, as this allowed STEM to assume control over Grey's mind and body. Grey's consciousness believes the idyllic dream state it has found, while STEM kills Cortez and leaves.
