The CSI team works to close Grissom's last open case, the "Dick & Jane" murders, as Grissom prepares to leave the team for good. Before leaving, Grissom offers Dr. Raymond Langston, who helped the CSI's with the "Dick & Jane" case, a permanent position as part of the CSI team.
Picking up where "19 Down" left off, Brass identifies the new victim found under the bridge as Jeffrey Masters. His wife Maureen is missing, and Brass estimates that the team only has at most 48 hours to find her alive. After the Sheriff is briefed by Brass and Ecklie, Ecklie, who is slated to step into the Undersheriff position, tells Grissom that the sheriff has personally requested he stay on until the conclusion of the case. Continuing to work with Dr. Ray Langston, the professor whose class Nathan Haskell was speaking to from jail, the CSIs focus on what drugs Haskell might have used to subdue his male victims. Positing that Haskell had an accomplice in Langston's class, the CSIs also turn their attention to Langston's students. Brass speaks with Dan Forrester, the student who suggested getting a serial killer to talk to the class and corresponded with Haskell, but when he realizes he is a suspect, Dan tells the detective the idea came from multiple students in the class. The team visits Langston's classroom and plays the video of Haskell speaking to the class, trying to pinpoint if he made eye contact with any of the students during key comments. They zero in on a student named Thomas Donover, who asked Haskell how he controlled his victims and was told where to dump Jeffrey Masters. The police find him missing when they go to his house, and his wife Kelly insists that she does not know where he is. The CSIs search the Donover house and Greg finds shoes that match the treads found at the scene of Ian Wallace and Justine Stefani's murders. Tom is definitely the accomplice. While Tom torments Maureen, the CSIs race to isolate the location of the house where Haskell took his victims—and where Tom likely has Maureen now. Hodges discovers a kind of moss stuck in the tread of Tom's shoe that at least narrows their search to the north side of Lake Mead, but that still leaves the CSIs with a lot of ground to cover and not much time in which to do it.
Nick finds a box of video tapes in Tom's house—but no VCR around and recalls that Gerald Tolliver had a VCR but no tapes. Kelly confirms Tolliver was a friend of her husband. Catherine finds a type of sage (Salvia Divinorum) at Tom's house amongst his drugs stash that Henry confirms could have been used to subdue Haskell's male victims as it's a powerful hallucinogen. A print leads them to the dealer, but he's killed (run over accidentally) when he runs from the police. Nick views the videotapes and see Haskell's first victims, Joel and his fiancée Tiffany, with Tom Donover and Gerald Tolliver—and later spying on and filming Haskell. Grissom consults lunar charts hoping to find a way to identify the location of the house, while Langston pays Haskell a visit in jail, hoping to get the information out of him by showing him stills from the video tape spying on him. He tries to trick Haskell into thinking they already have Tom and Maureen and just want the location of the bodies of his female victims, in the hopes he betrays the location of the cottage, but Haskell sees right through his ruse and gives him nothing. Grissom uses the state/direction of the moon in the videos to find the house's location and discovers it is in Black Mesa. Brass and his team rush there and Tom is killed by a shot to the head just as he is about to murder Maureen. Brass frees her and the CSI team canvasses the house and Grissom discovers the bodies of Haskell's female victims stashed side-by-side under the floorboards of the house. The case closed, Grissom visits Langston at WLVU and suggests he apply for the new vacancy at CSI, to which he answers he'll think about it. Grissom finishes packing up his office, and despite an impassioned plea to stay from Hodges, exits CSI, catching only Catherine's eye as he walks past the team hard at work. Grissom heads to Costa Rica where he reunites with Sara Sidle as she's photographing some monkeys, kissing her passionately. She looks surprised but elated to see him as they embrace...

- This episode marks the last official appearance as a series regular by William Petersen (Gil Grissom).
- When Grissom throws down his backpack, Sara is holding her camera on the carrying strap. But just a second later in the same scene, she has a grip on the camera's lens when they're embracing and kissing.
- The coordinates on Grissom's GPS Device don't point to Costa Rica as displayed, but rather somewhere near Arauca in Colombia, some 1000 miles offset.
- The tracking shot of the camera on the jungle's trial disturbs the vegetation causing movement of leaves and small branches.
David Hodges (Walks in as Grissom is cleaning out his office): Okay. So this is really real. Fine. So, as your friend and colleague I feel that it's my obligation to inform you what a colossal mistake you're making.
Gil Grissom: Hodges...
David Hodges: Guys like us just don't get to hang it up. This job is who we are. We are the tin blue line between order and chaos. You take yourself out of the equation, who knows what's gonna happen. That's the Butterfly Effect. You taught me that. The bad guys will win more if we don't have you. Who is Watson without Sherlock Holmes?
Gil Grissom: Watson was a genius in his own right...It's the right time for me to go.
David Hodges: Okay.
Gil Grissom: A penny for your thoughts?
Dr. Raymond Langston (Pointing up to where Tom Donover was sitting): He was sitting right here. He was looking at me, I was looking at him. All I saw was another student.
Gil Grissom: That's all I saw.
Dr. Raymond Langston: I guess I'm tired of getting fooled.
Gil Grissom: People lie, Professor. The only thing that we count on is the evidence.
Dr. Raymond Langston: Thank you for letting me help. It was......
Dr Raymond Langston: Well, it was something that I really needed to do.
Starts to walk away
Gil Grissom: Hey
Langston turns around
Gil Grissom: I don't know if you'd had any interest, but we have a job position open in our lab.
Dr. Raymond Langston: You're serious? I can't imagine myself as a cop.
Gil Grissom: We're not cops. We come from a wide variety of backgrounds. You're a medical doctor. You're totally qualified. It's an entry level position. The hours are terrible, the pay is bad.
Dr. Raymond Langston: But money's not exactly the object, is it?
Gil Grissom: I think that you'd be a great help to CSI and you might really enjoy it.
Dr. Raymond Langston: I'll think on it.
Nathan Haskell: Professor Langston, how good to see you. What brings you here?
Dr. Raymond Langston: I came to gloat.
Sets photos on the table
Dr. Raymond Langston: Please, come in, Nate...We got these frome a videotape of one of your kills. It's hard to believe isn't it? Now, in all fairness, you did say that only dummies take souvenirs and Gerald Toliver was a pretty dumb guy. Maybe that's why Tom Donover killed him. You know, I've been thinking that maybe, that's the reason Tom Donover decided to follow in your footsteps, and carry on your work...
Dr. Raymond Langston: Anyway, none of that really matters know, because...
Starts laying out more photos
Dr. Raymond Langston: As you can see, we found your house in Lake Mead and we have Tom and the girl, she's alive.
Nathan Haskell: Than what do you need me for?
Dr. Raymond Langston: Closure. You once told me you've been thinking about it a lot, well I've been thinking about it, too. I need you to tell us where the girls bodies are buried, Nate.
Nathan Haskell: I see. So you're working with that cop now?
Dr. Raymond Langston: We're gonna find them eventually, you know that. We'll dig, we'll dredge the lake, we'll tear that house of yours down to the studs if we have to. Now, why don't you save us the trouble? Tell us what we need to know. Look, maybe I could get something out of it for you.
Nathan Haskell: Like what? You gonna reduce two consecutive life terms down to one?
Dr. Raymond Langston: Like maybe I could guarantee that this isn't the last conversation that you'll have with someone who isn't shoving your food through a hole in the door. I promise you, Nate, you don't tell me what I need to know and the only person who will hear the sound of your voice again is gonna be you.
Nathan Haskell (think): You follow the fence in the back yard
Dr. Raymond Langston: To where?
Nathan Haskell (Realizes Langston is bluffing and he doesn't know where the house is or where the girl is): To where, what? There is no fence in the backyard... You thought you could make me slip up again and give you something you want. You thought that you could get inside of my head? A person has to do what I've done to understand me. You have no idea what I've started. I'm a teacher too. My students are everywhere, they're out there. I'll cut them free, I'm spreading the word, by the time you find them it'll be too late and there will just be more blood on your hands.
Dr. Raymond Langston: Get him out of here.
Nathan Haskell (Cops are dragging Nate out of the interview room): She's already dead
Dr. Raymond Langston: Get him out of here!
