There is a major police chase after an armed suspect, as he holes himself up in a row house that is the headquarters of ARM (African Revival Movement). The head of that house, a former cop, calls in a favor, high in the police department. Munch and Pembleton try to work the case as Bayliss seems to be missing. Their investigation seems to be thwarted every step of the way. Stivers' has second thoughts about what she saw at the Mahoney shooting. An attempt to serve "Burundi" Robinson an arrest warrant breaks out into a war between the police and ARM. Gee goes into the house to confront Robinson and finds out who and what he knows.
