When a witness who testified against D'Angelo Barksdale is discovered murdered, McNulty and the detail take the opportunity to link the killing to Avon Barksdale's drugs crew.

Gung-ho tactics from Herc, Carver and Prez result in a riot, innocent casualties and bad publicity for the new department. Meanwhile, Bubbles the snitch introduces an undercover officer into the projects, and the detail plans a raid on Barksdale's supply.

The team's raids prove wholly unsuccessful. McNulty cannot convince any of the suspects to give up Barksdale, and Bodie manages to escape from lock-up.

When the detail discover that Barksdale's drug crew uses pagers to communicate, McNulty becomes determined to get hold of one to listen in on the organisation.

When a sting operation goes awry, the police go after Barksdale's foot-soldiers once again. With one eye on the press, Daniels orders a city-wide series of raids; while Freamon discovers that there is a rat in the detail.

Herc discovers a blast from his past, which he later reveals to his colleagues. Daniels becomes enraged when he finds out that his detail was reassigned. Stringer Bell finds out from old girlfriend Donette that Brianna might contact McNulty with details of her son D'Angelo's death.
