Rita takes the kids out of town for the weekend, leaving Dexter time for some much needed R&R. And for him, that means stalking a new victim. He sets his sights on a woman accused of murdering her family - a fellow cop, no less. The more Dexter learns about this woman, the more he begins to question his own judgment. Can Dexter handle the pressures of family, or is he headed down a similar dark path?
Meanwhile, LaGuerta and Batista argue over department protocol, which threatens their professional relationship. And Debra aids Lundy in his quest to find the Trinity Killer, neither of them realizing just how close Trinity is to achieving his goals.
