Plot
The episode opens with the castmates eating "breakfast tacos" in the Craft Services Tent. Harold bites onto something unusual in his breakfast, which turns out to be a flash drive. Beth suggests putting it into Courtney's personal digital assistant to find out what information it holds, but an annoyed Courtney tells Beth that her PDA isn't going anywhere near it. Duncan grabs it and then reminds her that if she wants to win, she'll have to play along. She concedes, and the technology is inserted into her PDA. It shows a video of Chris subtly giving the contestants clues to use to open a safe. Lindsay suspects that Chris is dead, since Chris mentions that he was on cloud nine and goes on to say that since the common thing to do with dead people is bury them, they should start to dig. Courtney eventually figures out what the clues actually mean and leads the contestants to the safe from Ocean's Eight - Or Nine. Using the numbers that Chris said in his video, Courtney opens the safe, which Chris is inside of. Courtney then demands a prize from Chris, but Chris says that he never said this was the challenge and simply thanks Courtney for freeing him.

Chris then explains to the contestants that throughout the day, they need to collect DNA samples from their fellow contestants. They then leave to start the challenge. Lindsay and Courtney are shown getting into an argument, which Courtney resolves by offering Lindsay a spa treatment. Courtney then tricks Lindsay into giving her a DNA sample. Duncan is then shown leaving the trailer and almost getting caught in Harold's incredibly complex trap. Duncan then finds Harold hiding in the bushes, waiting for the trap to work. Duncan then jumps him and gets a DNA sample from him.

Courtney is then shown going to take a shower. Lindsay attempts to get her footprint by getting Courtney to walk in paint and then on a sheet of cardboard, but Courtney drenches it with water, ruining it. She pats Lindsay on the back for trying. Next, Beth is shown tricking Lindsay into giving up her DNA sample by pretending that her retainer has fallen into some spaghetti. Then, in the confessional, Harold gets a DNA sample from Beth, after attempting to get a sample from Duncan again. Courtney is then seen tricking Duncan into giving her another sample, although she did it simply for the joy of it, as she had already collected Lindsay's DNA. The contestants are then seen giving up their samples to Chris. Lindsay is the only one with no samples at all. Upon giving Chris two samples, Courtney demands a prize. Due to her persistence, Chris ends up giving Courtney a bag of cheese puffs that he was going to have on the train, just to shut her up. The contestants then go onto the train.

While on board, the contestants are submerged in darkness, and Chris shouts to someone that they "can't kill the host." The lights suddenly turn back on, and on the floor of the train lies the dead body of Chris. The contestants are frightened and Courtney demands that Harold perform CPR on Chris. The action does not work, and Beth and Harold are shaken. Lindsay then compares the situation to her trip to cheering camp. Courtney ignores her and convinces Duncan to climb on top of the train car, which she is convinced is fake, like the airplane in Full Metal Drama. Duncan then proves that the train is indeed a real train when it goes under a tunnel while he is on top.

While Duncan is outside of the train, the lights turn off once again, and Chris' body disappears. Harold finds one of Duncan's green hairs where the body used to be, and the contestants (with the sole exception of Courtney) immediately blame Duncan for the disappearance, prompting them to handcuff him to a guardrail in the car. Courtney objects and insists that the rest of the contestants should stop listening to Lindsay. She then manages to get Harold to assist her in trying to stop the train so they can get off of it, while Beth and Lindsay continue to work as a separate team.

Eventually, Beth decides to assist Harold and Courtney, as well. However, while they are attempting to get off of the train, Lindsay discovers a napkin with Courtney's finger prints on it. Thinking that Courtney had used the napkin as a murder weapon, Lindsay explains how Courtney is guilty to the rest of the cast, since she was the only one with access to cheesy puffs, and the fingerprints were composed of cheese powder. Courtney protests, insisting that she is innocent, but to no avail, just as the contestants are about to handcuff Courtney, Chris walks back into the compartment. He announces that Lindsay won the challenge, much to Courtney's dismay. Chris then tells Lindsay that she gets to choose someone to take to the movies with her, as her reward. She chooses Duncan, in order to make Courtney jealous, and Duncan agrees, to see how jealous Courtney will become. Even Beth, in a confessional, admits that she doesn't mind Lindsay's choice of Courtney over her because Courtney's jealousy would be very interesting to watch. As expected, Courtney turns out to be very jealous and although she initially attempts to deny it, she breaks down and starts crying in the confessional. Chris then signs off the episode, after admiring his rubber replica.

Exclusive Clip
Lindsay compares going to the movies with Duncan with ordering the Mega Combo at the movies. At first everything is working out fine; Courtney is losing her mind, Duncan is "pretty okay" most of the time and the butter is glistering off the popcorn. But she then states by the time the previews are over, she already finish both her popcorn and drinks and starts to gets sick.

Cast

 * This episode shows a great deal of friendship between Duncan and Lindsay, more so than any episode prior to it.
 * This is notably the first episode of Total Drama to make hints of a person smoking, though it was not real.
 * This episode contains many similarities to Hook, Line, and Screamer, such as:
 * Courtney dismisses everything as fake, similarly to Heather in that episode.
 * Chris pulls numerous stunts to really make everything seem real, similarly to his unexpected exit from the island.
 * Murder plays a major part in this episode, similar to the killer "butchering" campers in the episode.
 * This particular aspect is also similar to I See London....
 * The zombies that Chris fights are zombie-like versions of the cameramen from Riot On Set and Total Drama, Drama, Drama, Drama Island. These two cameramen are based off of Duncan and DJ's Camp TV design.Badminton- The Movie.png

Continuity

 * This episode marks the first episode in which Courtney hasn't won the challenge or immunity since she joined the competition in Total Drama Action. It is also the second time Lindsay wins the reward since the merge.
 * This episode shows Chris' movie that he talked about in Million Dollar Babies.
 * This is the second episode where Duncan has mentioned Bigfoot. The first is The Princess Pride.
 * This is the second episode that mentions that Courtney watched Total Drama Action prior to her debut into the competition. The first is One Million Bucks, B.C..

Goofs

 * When Lindsay is in the confessional, her hand vanishes for a moment.
 * When Beth grabs the handcuffs, they have a chain link between them, but when Duncan is cuffed to the door, they have a metal rod between them.
 * When Chef wheels in the cart full of snacks there is no soda, but later there is, when the contestants throw soda into the wheels.
 * When Duncan goes on top of the train and falls back down, his green mohawk is damaged, but after he comes back from another room to look for Chris, his mohawk is back to its original state.
 * Beth screams in this episode, but she said she couldn't in The Sand Witch Project. This has been a recurring goof throughout the season.
 * Even though Chris says Courtney has her own bathroom in One Million Bucks, B.C., Courtney was shown showering in the communal bathrooms in this episode.
 * The napkin being used as the "murder weapon" would imply that Chris was suffocated, however, when the lights went out, there was the noise of something being smacked and shot at and no gasping for air, implying Chris was smacked with something instead.
 * When Courtney hands in her evidence, she is seen to have two sets of hand prints and hair samples. However, she only collected Duncan's hair, not his hand print.
 * When Chris paints Courtney's hand on the train, she puts her hand down, but when she is shown again there is no paint on her hand at all.
