[17] After witnessing the murder of Elliot Sully, his CFO and friend, genius billionaire Gideon Reeves of Reeves Industries makes a proposal and deal with the mayor to get the troubled Chicago Police 13th District and upgrades it with his company's latest technology, notably by creating the APB app that allows citizens to immediately alert the police to a crime, bulletproof cars and improved weaponry.

Gideon modifies the police force's motorcycles to go faster in order to outpace and capture the thief, who happens to be a race car driver by profession.

The 13th District responds to a call from Murphy's friend, Linc, a retired cop turned security guard who used the APB app before he was killed by five jewelry thieves armed with AR-15s.

When they capture one suspect who doesn't give up any information, Gideon redesigns a chair that uses biometric feedback sensors to measure stress levels and tests it in the interrogation room.

When Brandt goes undercover to collar an illegal weapons dealer (Tim Griffin) who has been supplying armor-piercing bullets to the drug dealing community, a problem arises with how to get a wire into the meeting.

A fellow MIT grad goes to great lengths to get a meeting with Gideon, hoping that he and the officers of the 13th can take down the people dealing a dangerous new synthetic drug that has harmed his daughter.

Gideon's con man father Joe (John Heard) gets in trouble with a mobster and turns to his son for help in exchange for aiding the 13th precinct in their takedown of the crime family.

Gideon is the keynote speaker at the Windy City Tech Summit, where he is joined by Lauren (Kim Raver), the CEO of Reeves Industries.

When an FBI informant working within a drug cartel is feared to be dead on a boat sunk in Lake Michigan, Gideon retrieves a $50 million submersible he developed for NASA to explore the wreckage.

Meanwhile, Danny Ragabi (Ty Olwin), a hacker from Ada's past now known as DV8, wants to disrupt the work of the 13th Precinct, as he believes Gideon is creating a police state.

With the neighborhood community not cooperating with the police, Conrad, Murphy, and Gideon are stuck with collaborating with the drug dealer to find ways they can work together to expose and collar the rapist.

The website's consensus reads, "APB's reliance on high-tech gadgets at the expense of high-stakes drama makes it a cutting-edge police procedural not worth watching.
