Dexter has always known his father’s Code was meant to protect him from exposure. But after committing a serious mistake, he wonders if it could have been designed to protect him from something even more dangerous – human emotion. When he discovers that Trinity is planning an out-of-town trip, Dexter sees an opportunity to ride along and gain insight into the mind of a fellow monster. Even so, Dexter isn’t prepared for the startling revelations Trinity makes along the way, revelations about his own past which only serve to convince Dexter of what he must do. Meanwhile, back at Miami Metro, Debra refuses to let a technicality keep her off the Trinity case. She works through others to ensure her voice is heard – that is, until she realizes that her single-minded pursuit of the Trinity Killer may have blinded her to the truth.
Dexter finds himself enjoying a brief moment of tranquility. He’s finally managed to strike a balance between work, family… and other pursuits. But he’s keenly aware that times like these aren’t meant to last. When Miami Metro discovers a string of murders connected to a prominent photographer, Dexter sees an opportunity for a clean kill. However, his plans seem to be thwarted every step of the way. Quinn has taken a renewed interest in Dexter’s nightlife. Dexter’s plans to keep Astor and Cody distracted with new activities soon backfire. Even Harry disapproves of Dexter’s choice of pastime, urging him instead to focus his efforts on the Trinity Killer. Meanwhile, Debra returns to work, frustrated to find everyone treating her with kid gloves. She decides to concentrate on her pursuit of the Trinity Killer as well as delving into her father’s checkered past – investigations which Dexter fears might lead her to danger – or worse, the truth.
Dexter knows it’s only a matter of time before Miami Metro discovers the Trinity Killer’s latest handiwork. Therefore, he has to work doubly hard to stay one step ahead of their investigation. Dexter has begun to realize that the closer he gets to Trinity, the more he stands to learn from this very different beast. Trinity hides behind a well-kept mask, and getting behind that facade will require some extra prodding on Dexter’s part. Meanwhile, Debra becomes frustrated when she finds herself shut out from her own case. She considers bending the rules in the name of justice, risking her career in the process. LaGuerta and Batista come to regret a major decision, and realize that by playing by the rules they may have painted themselves into a corner. And when the friction between Rita and Dexter comes to a head, Dexter gleans relationship advice from a most unlikely source.
Recent events spur Dexter into his own investigation of the Trinity killer. His motivations are now personal, and the clock is ticking. But the closer Dexter gets, the more he realizes that Trinity is unlike any monster he’s previously encountered. Meanwhile, Debra blames herself for events that were out of her control, and in so doing pushes away those closest to her. As LaGuerta and Batista close in on the Vacation Murderers, Batista realizes he can use Quinn’s relationship with a certain reporter to his advantage. And when Rita discovers a secret Dexter’s been keeping from her, she begins to realize just how little she knows about the man she married.
Dexter’s house gets vandalized. There is spray paint everywhere. Rita and their neighbors have a neighborhood watch meeting in the living room. They decide on a plan to have their streets watched 24/7, which is going to make it difficult for Dexter to slip in and out to make his kills. Vandalism in the town gets worse, and Dexter suspects a teenager to be the perpetrator, but it turns out to be his father. Dexter confronts him and learns that his wife died and left his life in shambles and that he is no longer going to be able to pay rent. Dexter is relieved that he is leaving the neighborhood. On Dexter’s way back home, some motion-censored lights come on and he grabs a broom and breaks the bulbs. Rita see’s all this happen.
The Trinity Killer makes his next kill. He forces his victim, a mother of two, to stand at the edge of a building then falls to her death. Lundy thinks this killing involves the serial killer and Debra agrees. But Quinn and LaGuerta insist that, without more evidence, it is a suicide. LaGuerta tells Debra that if she wants, she can continue to investigate on her own, which means she would be spending more time with Lundy. She is convinces herself she is in love with Anton but the good time she has hanging out with Lundy makes her seriously reconsider her relationship with Anton.
LaGuerta and Batista’s relationship is starting to get complicated. LaGuerta is worried that they won’t be able to account for the time they spend together. Batista is more focused on keeping their relationship going. Quinn still thinks Dexter is going to tell someone about taking money from the crime scene. Dexter really doesn’t care.
