Four West Baltimore boys wrestle with what to do with the rest of their summer vacation as the new fall school year approaches. Bodie deals with his corner running slower than usual so he decides to take on a runner. Marlo believes he has finally solved the problem that Stringer could never figure out. Freamon, Greggs, and Sydnor go to Pearlman to see if she will issue City Hall subpoenas. Meanwhile, the mayoral race heats up as Mayor Royce and his primary challenger, Tommy Carcetti each hit campaign trail. Prez begins preparing for his new career in higher education, while McNulty ends up turning down a promotion.
In chronicling a multi-generational family business dealing illegal drugs and the efforts of the Baltimore police to curb their trade, this series draws parallels between these organizations and the men and women on either side of the battle.
The words of Gary W. Potter, Professor of Criminal Justice and Police Studies at Eastern Kentucky University, in writing about the savings and loan scandals of the 1980s, can also be used to illuminate some of the central premises of the show.
