Season 3 opens with Dexter tracking a killer who got away with murdering two college women, and winding up in a life-or-death struggle with a stranger who is in the wrong place at the wrong time. Debra investigates a high-profile homicide and gets pressured by an Internal Affairs officer, who wants her to snitch on a fellow cop; Angel gets good news about his career; Rita startles Dexter with some news of her own. ~ Ray Stackhouse, Rovi
