The series is produced by JJ Abrams, supervised by JH Wyman, the producer of Fringe, and produced by Bad Robot. The series is described as a "police drama with action and brotherhood as the main theme", and the story takes place in the near future 35 years from now. At this time, humanoid robots with high artificial intelligence have appeared, and all Los Angeles Police Department detectives are assigned a humanoid robot partner. They have to investigate cases related to humans as well as cases related to robots. But in many cases, human cases and robot cases are mixed together. In 2048, human society has evolved to a new level. Meet John Kennex (Karl Urban), a survivor of the most horrific attack on the police department in history. After being in a coma for 17 months, he finally woke up, but his memory of what happened at that time was vague. His partner was unfortunately killed in the incident, and his girlfriend Anna Moore (Mekia Cox) has left him. He lost a leg, and the doctor gave him a highly sophisticated artificial bionic leg. John is depressed, depressed, suffering from severe post-traumatic obsessive-compulsive syndrome and stress disorder, and he is full of rejection of his "bionic parts". Despite this, he returned to work at the request of the police captain Sandra Malconado (Lili Taylor). Sandra is his longest-known and most loyal friend, and he knows that she will never hurt him. According to the order of his superiors, every policeman must now partner with a robot. Although John strongly hates robots, he was assigned a machine partner-the MX-43 robot war police who had just been offline and was ready to go into battle. When this robot colleague discovered that John was hiding some evidence of a crime, John mercilessly "ended" him (refer to the trailer for related plots). So the laboratory technician Rudy Lom (Mackenzie Crook) introduced him to a new machine companion: Dorian (Michael Ealy). Because Dorian had an unexpected "emotional reaction", the police force stopped his qualification to perform the mission and recalled him to the laboratory for a careful examination. Although these "emotional reactions" seem to be nothing more than errors in Dorian's central nervous system, it is these "errors" that make John resonate with Dorian. After all, John is now "part robot" and Dorian is "part human". John and Dorian's mutual understanding not only makes them complementary at work, but also "connects" them to a certain extent. While adapting to his new partner, John must also learn to get along with his new colleagues-including Detective Valerie Stahl (Minka Kelly) who is eager to become famous and Detective Richard Paul (Michael Irby) who is always suspicious. Richard insists that John is responsible for the disastrous mission that killed many police officers that year, and he certainly does not welcome John to rejoin the police force. The show is a series with both unit elements and continuous elements (almost all JJ Abrams-titled series in recent years are like this)-John and Dorian will handle specific cases in a futuristic city in each episode, but the truth of the incident that year has always been a mystery to John. John's investigation around this mysterious incident and the stories related to it will drive the development of the main plot. Most of the other producers of the show came from the crew of "Fringe", and most of the screenwriters are also "official screenwriters" of BadRobot (who participated in the creation of "Fringe", "Person of Interest", "Revolution" and other shows). JJ Abrams once said in an interview that the show has the flavor of "Blade Runner".
