Chicago P.D. Season 12 nears its final stretch, Episode 15, titled “Greater Good,” delivers one of the most gripping storylines of the season. With tensions rising inside the department and the city under pressure to control crime, Intelligence faces its biggest challenge yet—one that could alter the power dynamics within the police force forever.
The Episode’s Central Conflict
The episode revolves around Sergeant Hank Voight as he becomes increasingly suspicious of Deputy Chief Charlie Reid, a high-ranking official who has been spearheading the controversial Violence Reduction Initiative (VRI). While the program is publicly praised for its efforts to reduce crime, Voight starts to uncover disturbing truths about its true nature.
Reid, once considered a powerful ally, is now appearing more like a calculated manipulator who is using the initiative to orchestrate backdoor deals with Chicago’s criminal underworld. By selectively enforcing the law, Reid ensures certain gangs thrive while others are eliminated, allowing him to control the city’s crime rate and maintain influence over key figures in law enforcement.
Voight, known for his morally ambiguous methods, is no stranger to bending the rules to get justice. But even he has limits—and what he is discovering about Reid crosses a dangerous line. With the help of Assistant State’s Attorney Nina Chapman, Voight begins to gather evidence to expose the corruption at the heart of the initiative.
The Stakes Get Higher
Throughout the episode, Voight faces mounting obstacles, both within and outside the department. Many officers are unwilling to challenge Reid, fearing career repercussions. Even members of Intelligence, including Hailey Upton and Adam Ruzek, warn Voight that going after someone as powerful as Reid could backfire.
Meanwhile, Chapman, who once clashed with Voight in the past, finds herself drawn into his mission. While she is determined to uphold the law, she also recognizes that exposing a senior police official could bring down the entire system—and that’s a risk few are willing to take.
Reid himself is no fool. He senses Voight’s suspicions and makes a veiled threat, reminding him that stepping out of line could cost Voight his badge, or worse. The tension between the two builds throughout the episode, culminating in a confrontation that feels like a battle for the soul of the Chicago Police Department.
The Explosive Ending
As the episode reaches its climax, Voight and Chapman finally obtain a key piece of evidence—a recording implicating Reid in illicit activities. They now have a choice: go public with it or wait for the right moment to strike.
In a powerful final scene, Voight visits Reid in his office, sliding the incriminating evidence across the desk. Rather than making an arrest immediately, Voight delivers a chilling warning:
“I don’t care how high up you are. I don’t care how many politicians have your back. Your time is up.”
Reid, unfazed, smirks and responds:
“Be careful, Hank. You might not like what happens next.”
The screen fades to black, leaving viewers with more questions than answers. Will Voight and Chapman successfully bring Reid down? Or has Voight just put a target on his own back?
What This Means for the Future of Chicago P.D.
This episode sets the stage for a dramatic power struggle in the remaining episodes of Season 12. With Reid exposed but still wielding influence, Voight and his team are in for an all-out war—one that will test their loyalty, ethics, and survival in ways they’ve never experienced before.
Moreover, the ending hints at a potential shake-up in the Intelligence Unit. If Voight goes too far, could this be the moment that forces him to step down? And if Reid retaliates, will someone in Intelligence pay the ultimate price?
