"all in the game..." - Traditional West Baltimore.

Every crew has weak links--including Avon Barksdale's. With the heat turned up in the high-rises, Daniels and McNulty turn to a higher authority in an effort to crack the case wide open. Season finale.

'The world is a smaller place now.' -- The Greek

Bodie's effort to improve sales ends disastrously, forcing Bell to rethink his strategy. Ziggy pulls Johnny Fifty into a new caper that should make the Greeks pay off big. McNulty, undercover and outnumbered in the brothel, awaits 'rescue.' Daniels and Pearlman stay cool as Valcheck fumes over the change of targets--and Burrell pulls the rug out from under him.

"Conscience do cost." -- Butchie

Herc discovers a blast from the past, which he belatedly reveals to his ex-colleagues. Daniels blows a gasket over the real reason the detail was reassigned from an investigation in Pimlico to the Western District. Stringer Bell learns from Donette that she's told Brianna about McNulty's visit and that Brianna is likely to talk to him.
