Ep 6. Some Friend

In episode 6 of season 4 of Chicago PD, titled "Some Friend," the episode begins with a violent carjacking, which soon turns out to be part of a larger string of carjackings. The Intelligence unit is tasked with tracking down the suspects behind the violent incidents, but they are also dealing with some internal concerns within their team.

In parallel to the investigation of the carjackings, Atwater is dealing with a personal issue that raises questions about his integrity. Voight and the rest of the team grow concerned with Atwater's secretive behavior and fear that a long-held secret could be revealed and compromise his ability to work as a police officer.

Meanwhile, Lindsay is approached by an old friend from her past, who asks for her help in finding her missing, drug-addicted sister. Lindsay, torn by her loyalty to her friend and her duty as a cop, struggles to balance the two and avoid crossing ethical lines that could put her job at risk.

As the investigation into the carjackings continues, the Intelligence unit uncovers a surprising link between the suspects and a major drug cartel. Voight and the team dig deeper into the cartel's activities and work to shut down their operations while also trying to prevent further violence on the streets of Chicago.

As tensions rise within the team, Atwater is forced to confront his past and come clean about a mistake he made while working as a police officer. His honesty and humility prove to be a significant turning point for the team, and they gather around him to offer support and understanding.

Ultimately, the team's hard work and collaboration lead to the capture of the carjacking suspects and a major bust of the drug cartel operating in the city. Lindsay, too, manages to navigate the ethical challenges presented by her friend's request for help and comes to a resolution that satisfies both her personal loyalties and professional obligations.

With the carjacking spree brought to an end and a significant blow dealt to the drug trade in the city, the team reflects on the challenges they faced both as police officers and as friends to one another. Through it all, they prove their commitment to justice and their unshakable loyalty to the people of Chicago.
