An armed murder suspect takes refuge in the headquarters of the African Revival Movement, a pro-social organization headed by a former Baltimore cop. In their investigation of the case, Munch (Richard Belzer) and Pembleton (Andre Braugher) are roadblocked every inch of the way -- even though the killer's victim was an A.R.M. member. When the crisis threatens to erupt in full-scale violence, Giardello (Yaphet Kotto) defies orders from his higher-ups and takes a hand in the matter. Meanwhile, Stivers (Toni Lewis) begins to question the circumstances surrounding the recent killing of drug kingpin Luther Mahoney. ~ Hal Erickson, Rovi
