Noland nimmt seine Nichte Amy für ein paar Wochen bei seiner Familie auf. Nach kurzer Zeit bemerkt er, dass Amy im Chatroom einen Jungen namens Icarus kennengelernt hat. Als Amy plötzlich spurlos verschwindet, befürchtet Noland, dass sie in die Fänge eines Pädophilen geraten ist.
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 aimerait bien que son ex-femme Sherry travaille à ses côtés. Le chef de la police décide d'instaurer un programme de réinsertion lancé par Ella, juste avant son décès, lorsqu'une femme en liberté conditionnelle est retrouvée morte. Pendant ce temps, Temple tend un piège à deux policiers.
Alcune adolescenti scompaiono dopo essere state attirate online da un uomo chiamato Icarus. Quando la nipote di Noland diventa una possibile vittima, il caso si fa personale per l'investigatore.
