Just another midnight shift for the Homicide squad, with yet another shooting in West Baltimore. But this time there is a witness who is naming names. And at 4:00 a.m., why are Col. Barnfather and Capt. Gaffney taking such an active interest in the investigation?

Felton's murder investigation involves the whole squad plus Falsone from Auto and Gharty from IID (Felton had been undercover). Actually, Howard and Russert are shut out because of their personal involvement with Felton. Gharty and Falsone discover they have both had the same snitch and hone in on his possible role in the murder.
