Life for Dexter is returning to normal. He’s taking care of his son with the help of Angel Batista’s sister Jamie. He dispatches two EMTs who have been killing patients to harvest their organs and he’s looking forward to his high school 20th anniversary reunion. Not surprisingly, Dexter was something of an outsider in school but one girl, Janet, was at least nice to him. She dated and eventually married the schools star quarterback Joe Walker but committed suicide after they were married. Dexter is certain that Joe killed her and his main interest in the reunion weekend is to get a DNA sample from him. Elsewhere, Maria LaGuerta has been promoted to Captain and she and Angel are divorced. They’re still friends and she is recommending him as her replacement as Lieutenant. Deb and Quinn are still living together and he is getting ready to pop the question – only to be interrupted in a restaurant in an unusual way. Finally, the entire squad has to deal with the disappearance of a roadside fruit seller. From the evidence at the scene, they think the man may have been disemboweled. When his body washes up on shore, they find something has been put into his torso.
Dexter lines up his next victim, Brother Sam a criminal who claims to have found religion and while still running his body repair shop, gives other ex-cons a chance at rehabilitation. Dexter isn’t buying any of it and is certain that Sam will be his worthy next victim. Doesn’t quite turn out that way. The investigation into the dead man with the snakes put into his torso advances when one of the students finds heavy metals in their system. The two men responsible for that killing continue their preparations. Deb meanwhile has a day to remember. Still getting praise from her colleagues over the restaurant shooting, Quinn has a surprise waiting for her in the refrigerator. It’s left to Deputy Chief Tom Matthews to spring the biggest surprise of all however.
Deb faces her first day as the homicide squad’s Lieutenant. She isn’t sure she’s made the right decision given that she not used to the administrative side of the job and the fact that she is also supervising her now ex-boyfriend Quinn. She also has to deal with Captain LaGuerta who seems to want to do both her new and her old job. The police find another body on the shore. The dead woman may have been a prostitute but it’s her missing tooth that sends Dexter to an old scrap book. He finds a newspaper clipping for a serial killer from Oregon who the press labeled the Tooth Fairy after the fact that he kept a tooth from each of his victims. Masuka shows intern Ryan Chambers some evidence from the Ice Truck Killer case. He also manages to ask her out on a date. Gellar and Marshal meanwhile have taken a jogger prisoner. Marshall tells the man he will have to repent for his sins.
Dexter is in awe of the latest display from the Doomsday killer: the Four Horsemen of the Apocalypse made up of mannequins and human body parts. Testing confirms that the human parts all came from the same body. Deb Morgan, in her capacity as the new Lieutenant in homicide, holds her first press conference which she concludes did not go well. She is certainly very blunt. Meanwhile, Geller is unhappy with Travis’ decision to go on a date with a pretty waitress. There’s a price to pay for that. Dexter has a family crisis when Harrison has a burst appendix. Back in the lab, Masuka finally learns what Ryan has been up to.
Dexter runs background checks on Travis and discovers that he was a former student of Gellar. Batista and Quinn go to the university where Gellar used to teach.
As Dexter is following Travis in the hope of finding Professor Geller, he learns of Brother Sam’s shooting. He races to the hospital to learn Sam is unconscious. He sets out to find the killer and is quite certain who the culprit might be. During a brief lucid period, Sam asks him not to avenge his death. Deb tells Batista to get Professor Porter down to Miami for further questioning but realizes the whole case is in jeopardy when she learns Quinn spent the night with her. At the police psychologists suggestion, Deb decides to throw a house warming party. Meanwhile, Travis seems to be having trouble following Geller’s orders and must decide what to do with the young woman they’ve kidnapped.
Having avenged Brother Sam’s death, Dexter gets some bad news from Deb – it appears the Trinity Killer has returned to kill his wife and daughter, leaving his son Jonah as the only survivor. Dexter knows that Trinity is lying in pieces at the bottom of the ocean and immediately suspects that Jonah may have taken over where his father left off. He sets off for Nebraska to confront Jonah accompanied by someone from his past. When he confirms Jonah’s role in the deaths, Dexter clearly has a choice to make. Back in Miami, the team gets a significant lead when they locate the girl Travis released. But with Dexter unavailable, the squad are missing a key expert to analyze what they’ve found. Travis stays with his sister and seemingly ends his relationship with Gellar. Captain Laguerta embarrasses Debra at a meeting.
Dexter returns to Miami after his road trip to Nebraska and get a frosty reception from Debra who has been under pressure to get results in the doomsday killer case. He does his best to make amends, but doesn’t share what he knows about Travis and Professor Gellar. Thanks to Masuka’s intern Louis, the police now have a list of 200 of Gellar’s former students living in the Miami area and the team fans out to interview them all. It doesn’t stop the Doomsday Killer from striking again with a new tableau: the Whore of Babylon. Meanwhile Capt. Laguerta takes a particular interest in the death of a high class prostitute and seems desperate to have the case ruled an accidental death.
Having rescued Travis at the church, Dexter now tries to figure out what the next tableau will be. With Travis having agreed to help him, Dexter gets him a room in a hotel to keep him safe. A clue from one of the paintings eventually leads Dexter to a Professor Casey, an avowed atheist. He tries to warn Casey about what may happen but the professor brushes him off, claiming to get threats all of the time. Unfortunately, the doomsday killer strikes again. When Travis disappears, Dexter traces him to the church. Dexter finds him alive but also makes a startling discovery. Meanwhile Batista takes Quinn to task when he fails to show up for work and apparently left his phone and gun behind in someone’s car when he left the strip club. Debra decides to reopen the case of the dead call girl despite Capt. Laguerta’s objections.
