For Dexter, life seems to be going well. His relationship with Rita and her kids is back on track. He's no longer under scrutiny at his day job as a blood spatter analyst for Miami Metro Homicide. And his night job as a serial killer is operating on all cylinders. So when he sets his sights on Freebo, a dope dealer and killer, it looks to be just another night of Dexter's dark justice. But things don't go as planned and Dexter must find a way to extract himself from a pair of problems that he created, both in his home and night life. Dexter also finds himself inexorably drawn to Miguel Prado, an Assistant District Attorney, who has a very personal reason to bring Freebo to justice. Meanwhile, Debra is put in a difficult situation when someone from Internal Affairs wants her to inform on her new partner, Quinn.
