With the fall of the Barksdale empire, and the ascent of a new young drug king in Baltimore, McNulty, Bunk and the rest of the detail continue to "follow the money" up the political ladder amidst a hotly contested mayoral campaign. Prez witnesses first-hand the role of inner-city education in the formation of youth as four students, Michael, Namond, Randy and Dukie, face dangerous decisions and adolescent angst in a city rife with the temptations of crime and easy money.
