Several murders at Houston construction sites seem to be the act of an angry local. However, an SOS signal suggests the killer may have a military background.

Valchek leaks details of the Braddock case to Carcetti, who contemplates how to best leak it to the press. The ensuing negative attention turns Royce against Burrell, who takes the heat, while Rawls comes to the rescue.

With Election Day approaching, the three mayoral candidates make last-minute appeals. Carcetti wrangles for votes as he responds to a potentially devastating smear, and Norris and Greggs get a lead on the Braddock case.

Pearlman and Freamon continue arguing over the subpoenas, as the election draws closer. Elsewhere, Carcetti drops a bombshell on Royce during their televised debate, while Herc makes a shocking discovery about the mayor himself.

On the trail of missing bodies, Freamon turns to a higher authority after being rebuked by Landsman, and Carcetti finds his erstwhile promises of prosperity undermined by the school debt.

After flexing his muscles around the city, Carcetti faces his first dilemma, when a group of ministers protest against Herc's mistreatment of one of their own. Later, the Mayor reverses. Burrell still has some cards left to play.
