After beloved Ella Farmer dies unexpectedly, all the members of the police district pay a tribute to her, remembering all the hard work and effort she put in her job. They pray together and miss her, knowing she'll be forever in their heart, and that no one can ever replace her as Mannion's right arm.

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

Mannion's determination to crack down on gangs puts Noland in the line of fire where he's shot and critically wounded.

Mannion investigates the murder of two young women, one of whom is identified as Debreno's sometime girlfriend, Maria.
