'... when it's not your turn.' - McNulty.

Baltimore homicide detective Jimmy McNulty gets into hot water and winds up assigned to a detail of narcotics outcasts charged with investigating drug lord Avon Barksdale and his powerful operation in Franklin Terrace.

The early-morning 'field interviews' by Herc, Carver and Prez result in a minor riot, a boy losing an eye and some bad publicity for the department.

Meanwhile, Wallace and D'Angelo struggle with their consciences after Avon pays them blood money.

"Come at the king, you best not miss." - Omar.

An unlikely source gives McNulty the tag of a car driven by Stringer Bell. Meanwhile, Greggs and Carver bust a congressional aide carrying dirty cash, but are forced to let him go. Omar earns his 'loose cannon' moniker.

"And then he dropped the bracelets..." - Greggs.

With Wallace in custody, McNulty and Daniels try to figure out what to do with him in the months before he testifies.
