"In a normal working day, US criminal investigator Flint Waters will surf the Internet, chat online with someone whose acquaintance he made a few weeks earlier, and exchange photos and videos. And every so often, Waters goes for stress counseling to try to get some of the images he's seen in a day's work out of his head, because the reality of his line of work is in sharp contrast to the attractive job description. Waters is an undercover agent who investigates online sex crimes against children."
