The season starts midway into the Major Case Unit’s unsuccessful investigation into the Barksdale criminal enterprise. With their recent efforts fruitless, ASA Pearlman and Lieutenant Daniels consider dropping the wiretaps, to the dismay of the squad. Meanwhile, Ellis Carver finds himself in command of an incompetent group of policemen in the Western district. Bodie Broadus, Poot Carr, and Puddin reminisce about their days living and working in the 221 tower before it is demolished in an effort to stifle the drug trade. At a Barksdale Organization meeting, new head enforcer Slim Charles suggests that more territory is required and should be taken by force if needed; Stringer Bell maintains that product is the cornerstone of their operation. Dennis "Cutty" Wise, a legendary enforcer, is released from incarceration with an offer of work from Avon Barksdale.
