Code 8 (2019 Film) - Wikipedia

In the early 20th century, the public becomes aware of people with superhuman abilities, known as Powers, resulting in the government passing a law requiring all Powers to register their abilities. Powers become key to the workforce, specifically noted as having helped build Lincoln City as "the city of tomorrow", creating an economic boom. However, as the Third Industrial Revolution begins, Powers are marginalized in the face of increased automation and mechanization.

By the 1990s, a crime syndicate known as the Trust has flooded the streets with an addictive drug called Psyke, made from the spinal fluid of trafficked Powers. Police departments begin using drone-deployed robots, called Guardians, and facial recognition software to combat Power-related crime while a citywide Powers ban is debated.

Connor Reed, a 26-year-old Electric (electrokinetic) looks after his mother, Mary, a Cryo (cryokinetic), whose ailment impedes her from controlling her powers. Due to their status as Powers, finding decent work is difficult, leaving them unable to afford treatment for Mary's condition. Connor makes ends meet by working as an unregistered day laborer alongside other Powers. Elsewhere in the city, a drug raid is conducted by detectives Alex Park and Davis on an apartment complex owned by crime lord Marcus Sutcliffe, the local agent of the Trust and a Reader (mind reader). Marcus is confronted by his superior Westley Cumbo and told to pay his cut to the Trust soon or face consequences.

Connor is approached by Garrett—Marcus' underling and a TK (telekinetic)—and his crew for a job, which turns out to be a robbery of a chemical plant. Connor shorts out an electrical fence in an impressive display of power, piquing Garrett's interest. He is introduced to Marcus and meets Nia, Marcus's apparent girlfriend. Park and Davis arrive at the robbery scene the next day and determine that the stolen chemicals are being used to cut Psyke, indicating Marcus is desperate for revenue.

Garrett recruits Connor for more jobs while training him to maximize his abilities and agrees to help him earn enough money to get Mary's treatment. Connor grows close with Garrett's crew—Freddie, a mute Brawn (super strength), and Maddy, a Pyro (pyrokinetic).

Marcus has the crew rob a bank to pay back the Trust, but the vault contains only a tenth of the money they expected. Wesley's Shifter (shapeshifter) assassin, Copperhead, attempts to kill Marcus for not honoring his debt, but Marcus's bodyguard Rhino, a Brawn with bulletproof skin, kills them. Nia reveals to Connor that she is a Healer, and only remains with Marcus to ease the effects of his Psyke addiction and pay off her imprisoned father's debt.

Mary's condition worsens, and the doctors tell Connor that they need to operate soon to save her. Park and Davis bring Connor in for questioning. Davis wants to plant evidence and coerce him into informing. Park cuts him loose due to lack of evidence. He is revealed to have a daughter who is a TK, and who fears she will be given up because of her difficulty with controlling her powers.

When Connor is released he goes to Garrett and suggests they rob a police-confiscated Psyke transport, which will make them $10 million. They bring the idea to Marcus, where Connor demands Nia heal Mary as payment, while Garrett wants to be made equal partners with Marcus.

On the day of the heist, the crew blocks the transport inside a no-fly zone, preventing backup by drones carrying Guardians. Although they manage to retrieve the Psyke non-lethally, Marcus's men execute police officers and betray them. They kill Maddy and fatally wound Freddie, while Rhino flees with the drugs. Connor tells Garrett that Marcus framed them because of Garrett's demands, and they part ways.

Connor contacts Park and offers up Marcus's hideout. The cops raid it while Connor and Garrett team up to fight and kill both Rhino and Marcus. Garrett takes the Psyke and encourages Connor to use Nia to heal his mother. She pleads with Connor to let her go, as her abilities force her to take the injury or disease onto herself. He takes Nia to the hospital at gunpoint to cure his mother, but changes his mind after having a flashback. Mary dies soon after.

Connor gives Nia his truck to leave the city, while Garrett hands over the Psyke to Wesley and takes over the drug trade for the Trust in Lincoln City. Connor visits his mother's grave before he surrenders himself to the police, while Nia has a tearful visit with her father. Meanwhile, the Powers Ban is being voted on while Park reluctantly accepts an award for the successful raid.
