Chris Raven (Chris Pratt) wakes up, or maybe comes to, sitting in a chair, his wrists manacled. He is in Mercy Court, presided over by an AI judge who gives him 90 minutes to prove that he did not murder his wife. If he is not successful, he will immediately be executed.

“Mercy” is set in the near future, when civil unrest has led to the development of the AI court, reversing the Constitutional presumption of innocence and right to counsel with a system designed for efficiency. It is “the ultimate deterrent.” Chris is the 19th person to be tried by the AI judge, who appears on screen as a female character named Judge Maddox (Rachel Ferguson).

Chris does not even remember where he was the previous day and learns from the “judge” that his wife has been stabbed to death in the kitchen, her body discovered by their teenage daughter, Britt (Kylie Rogers). The “judge” plays the footage for him, showing him leaving work to return home, insisting on entering despite his wife telling him not to come in. No one else came to the house during that time period. Chris, a cop who was instrumental in developing the AI court system and brought in the first case, now sees what it is like to be on the other side. As the clock ticks down, Chris has access to all of footage, recordings, and records that are automatically stored online and is permitted to make calls to witnesses.

Producer/director Timur Bekmambetov specializes in action with a fantasy element like “Night Watch” and “Abraham Lincoln: Vampire Hunter” and that makes him a good fit for this film. We might not expect a movie set primarily in one spare room with a screen and a chair to be in IMAX 3D, but it keeps the visuals from feeling claustrophobia-inducing as Chris and the judge call up images of all of footage and data Chris calls up on the screen. Chris has an immersive experience, and the effects make us feel a part of it.

The set-up is strong, raising questions (though not spending much time exploring them) about how society balances safety and justice and imposing a tight time limit to build and sustain a feeling of urgency. Adopting if not reaching the ingenuity of telling the story on a screen of the innovative films “Searching’ and “Missing,” produced by Bekmambetov, he makes the best of that form of storytelling and Pratt does very well stuck in a chair, showing us how his character shifts from horrified, confused, and humiliated to the determined problem-solver cop he is.

The last part of the movie gets over-complicated, piling detail upon detail, and cutting some logical corners. But Pratt is, as always, a likable presence and we want to see him work through this mess and prove that he is innocent — and that at least for now humans can still outthink machines.

Parents should know that this movie included the murder of a mother, discovered by her daughter who is very traumatized, as well was peril and violence including guns, explosives, and a car chase, with characters injured and killed. Characters use strong language, some are alcoholics who struggle to stay sober and one starts drinking again and gets very drunk, there is brief drug use and reference to making and distributing drugs.

Family discussion: Do you think AI will ever be able to judge someone’s guilt? Did you think Chris was guilty and if you did, what changed your mind?
