"You cannot lose if you do not play." - Marla Daniels

The witness who testified against D'Angelo winds up being a murder case for "Bunk" Moreland.

McNulty and Bunk pick up D'Angelo for questioning and convince him to write an "apology" to the victim's family. Just as he's about to start, D'Angelo's attorney arrives and makes him leave. Meanwhile in "The Pit", Detective Greggs gets some inside information courtesy of Bubbles. New investigation team member Prez arrives with a heavy reputation of incompetence, which worries Lieutenant Daniels. Daniels's concerns are supported when Prez teams up with Herc and Carver to make their own moves in the case by going to the projects to "bust heads" for information. Things backfire and a quasi riot ensues.

While he's gone Bodie, Stinkum and the crew go to retrieve the new supply only renegade dealer Omar and his crew get there and steal the drugs for themselves.

After getting chided by his superiors, Lieutenant Daniels mobilizes the team to raid "The Pit".
