Dressed in Kevlar vests, Felton, Howard, Bolander, Munch and uniforms descend on an apartment building with an arrest warrant for Glen Holton, a pedaphile and the alleged killer of Billy Borkin. Howard, the primary, insists on going through the door first. As they approach Apartment 201, a silhouette on the third-floor staircase raises two semi-automatic handguns and shoots. Howard, Felton and Bolander are seriously wounded.

Barnfather gives the unit 48 hours to find the shooter. Lewis runs names of the apartment tenants through the computer and finds that Gordon Pratt, who has a record of weapons violations, lives in Apartment 201, the residence the detectives mistakenly tried to enter. Drummond, Walker, Pembleton and Bayliss search Pratt's apartment. They find teflon bullets and heavy-weather gear. Pembleton, Walker, Lewis, Munch, Bayliss and Drummond take turns interrogating Pratt. To get a confession, Pembleton gets the suspect, a racist, to lose his cool over questions of intelligence. But Pratt calms down long enough to ask for a lawyer. He is released on bond for the assault charge. Later, Bayliss responds to a call at Pratt's apartment building. He finds Pratt dead; no other police officer responded to the call.
