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

While Proposition Joe shows off his vocal range, Chris shows Snoop how to expose, and dispose of, New York infiltrators. Colvin uses "corner" logic in class. A newly sober McNulty attends an Irish cop wake - with a not-so-sober Bunk. Michael is dismayed by the unexpected return of a missing family member.
