The new Chief Strickland orders a drug raid and causes the death of an elderly woman due to inaccurate information on the location of a dangerous drug lord. Mannion sees a chance to get his job back and decides to catch the guy himself. He uses the help of his best men, who put their jobs at stake and work parallel to Strickland's orders. When Mannion finally catches the guy, Mayor Douglas won't give his job back, forcing Jack to reveal he knows the phone wiretap was illegal, ultimately forcing Douglas to give him his job back. Kids firebomb Mannion's apartment after he keeps stopping them from selling drugs. Meanwhile, Temple investigates two cops he thinks are abusing their authority and beating the people they arrest. At the same time, Debreno sleeps with Maria Rodriguez, which causes conflict in his friendship with Temple.

Chief Mannion and his men investigate the disappearance of teenage girls who all point to a virtual suspect: a guy named Icarus who uses internet chat rooms to lure his victims and eventually murder them. The case takes a personal turn when Noland's twelve-year-old niece becomes the next target. Icarus convinces her to run away from home with him, and Joe puts all his efforts into catching the guy. Meanwhile, Temple suffers from pranks and rash commentaries from his co-workers about the death of Lester Richards, while Sherry tries to adjust to her new job.
