The Wire - Season 2-c2c

The second season, along with its ongoing examination of the drug problem and its effect on the urban poor, examines the plight of the blue-collar urban working class as exemplified by stevedores in the city port, as some of them get caught up in smuggling drugs and other contraband inside the containers that their port receives. In a season-long subplot, the Barksdale organization continues its drug trafficking despite Avon's imprisonment, with Stringer Bell assuming greater power.
McNulty harbors a vendetta against his former commanders for reassigning him to the marine unit, a job he'd feared being assigned and hates. When thirteen unidentified young women are found dead in a container at the docks, McNulty makes a spiteful effort to stick the murders within the jurisdiction of his former commander. Meanwhile, police Major Stan Valchek gets into a feud with Frank Sobotka, a leader of the International Brotherhood of Stevedores, a fictional dockers' union, over competing donations to their old neighborhood church. Valchek demands a detail to investigate Sobotka. Cedric Daniels is interviewed, having been praised by Prez, Major Valcheck's son-in-law, and due to his work on the Barksdale case. He is eventually selected to lead the detail assigned just to investigate Sobotka. Daniels is assured that when the investigation is successfully concluded, he will move up to head a special case unit with personnel of his choosing.
Life for the blue-collar men of the port is increasingly hard and work is scarce. As union leader, Sobotka has taken it on himself to reinvigorate the port by convincing politicians to support much-needed infrastructure initiatives. Lacking the funds needed for this kind of influence, Sobotka has become involved with a smuggling ring. Around him, his son and nephew also turn to crime, as they have few other opportunities to earn money. It becomes clear to the Sobotka detail that the dead girls are related to their investigation, as they were in a container that was supposed to be smuggled through the port. They again use wiretaps to infiltrate the crime ring and slowly work their way up the chain towards The Greek, the mysterious man in charge. But Valchek, upset that their focus has moved beyond Sobotka, gets the FBI involved. The Greek has contacts inside the FBI and starts severing his ties to Baltimore when he learns about the investigation.
After a dispute over stolen goods turns violent, Sobotka's son Ziggy is charged with the murder of one of the Greek's underlings. Sobotka himself is arrested for smuggling; he agrees to work with the detail to help his son, finally seeing his actions as a mistake. However, the Greek learns about this through the FBI and has Sobotka killed. The investigation ends with the fourteen homicides solved but the perpetrator already dead. Several drug dealers and mid-level smuggling figures tied to the Greek are arrested, but he and his second-in-command escape uncharged and unidentified. The Major is pleased that Sobotka was arrested; the case is seen as a success by the commanding officers, but is viewed as a failure by the detail.
Across town, the Barksdale organization continues its business under Stringer while Avon and D'Angelo Barksdale serve prison time. D'Angelo decides to cut ties to his family after his uncle organizes the deaths of several inmates and blames it on a corrupt guard to shave time from his sentence. Eventually Stringer covertly orders D'Angelo killed, faking it as a suicide. Avon is unaware of Stringer's duplicity and mourns the loss of his nephew.
Stringer also struggles with the loss of his drug suppliers and bad quality product. He again goes behind Avon's back, giving up half of Avon's most prized territory, "the towers", to the eastside Baltimore drug lord Proposition Joe in exchange for a share of his supply. Avon, unaware of the arrangement, assumes that Joe and other dealers are moving into his territory simply because the Barksdale organization has too few enforcers. He contracts a feared assassin named Brother Mouzone. Stringer deals with this by tricking his old adversary Omar into believing that Mouzone was responsible for the vicious killing of his partner in their feud in season one. Seeking revenge, Omar shoots Mouzone, but realizes Stringer has lied and calls 9-1-1. Mouzone recovers and leaves Baltimore, and Stringer is free to continue his business with Proposition Joe with new consent from Avon Barksdale.
