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.
