This episode opens to the first class compartment, where there is definite tension among Team Amazon. Courtney and Sierra are planning on eliminating Gwen from their team the next time they lose a challenge. The reasons are as follows: for Courtney, Gwen's kiss with Duncan in the confessional (which resulted in her breaking up with Duncan by throwing food at him and kicking him in the groin); for Sierra, Gwen getting together with Courtney's boyfriend, as she believes boyfriend stealing is wrong. The only person having fun with all of this drama is Heather, who is just glad that the target is finally off her back, and thanks Gwen for becoming the new one in the confessional. In economy class, Team Chris Is Really Really Really Really Hot is planning their own next elimination, with Tyler and Alejandro hoping to eliminate Duncan.
The camera then shows Ezekiel and Chef's inflatable dummy sitting in the cockpit while the plane is on auto-pilot. Suddenly, two UFOs appear and shoot strange electricity beams at the plane, which causes it to waver in its flight. Chris calls the "potential crash victims" to visit the culinary for a "last meal" while their autopilot tests some of the equipment. Alejandro takes advantage of the turbulence to suggest that Courtney flirt with Tyler to make Duncan jealous and Courtney does so, mentioning that Tyler is "super-cute". This surprises Tyler, but he refuses to cheat on Lindsay, saying he could never do that to her.
The plane finally lands and Chris explains that they are in Area 52 - just next to the famous Area 51. There, he explains the challenge: Break into Area 51 and bring back an intact alien artifact. Team Chris Is Really Really Really Really Hot and Team Amazon reach their respective sides of Area 51 and form plans to get across, with Gwen accidentally leading Team Amazon to a mine field and Team Chris Is Really Really Really Really Hot losing Owen to the Black Ops. Team Chris Is Really Really Really Really Hot gets past the lasers first, while Team Amazon is forced to sing. Ignoring the girls' insulting Gwen in their song, Boyfriend Kisser, Cody throws his candy at the mine field, triggering the land mines and allowing his team to run across the field unscathed. Both teams enter Area 51's secret warehouse at the same time.
Both teams go off looking for intact relics. Heather is angry to discover that Courtney is purposely throwing the challenge in hopes of eliminating Gwen, while Tyler forces Team Chris to help him look for Owen, who may be having his memory erased. Alejandro angrily claims that an artifact won't fall from the sky, but Tyler causes a small box to fall into Alejandro's arms, releasing a pair of aliens that electrocute the both of them. Duncan and Gwen run into each other in the warehouse and Gwen mentions although everyone on her team now hates her, she enjoyed their kiss. However, she points out that Courtney's "ridiculous" flirting seems to be getting to Duncan, but before she can go on, Duncan kisses her, popping his foot up in the process. Gwen asks if Duncan kissed her just to shut her up, and Duncan says that is not entirely the reason. The two smile and decide to start a relationship and just let things happen. They are interrupted by an alien spaceship, reminding them they are competing against each other. Duncan runs off to capture the alien, and Gwen trips him. She tells him to try not to get eliminated, and Duncan replies with, "same to you", with a dreamy expression.
Cody is shown to be searching alone. However, when he finds an alien pod, an alien Cody is created as a result. Sierra is enthusiastic and hugs both so tight, the alien Cody explodes, covering Sierra and Cody in slime. Duncan finds Team Chris Is Really Really Really Really Hot and rescues them, but makes Alejandro promises not to vote him off in return - he fails to free Alejandro, but they both end up unintentionally freeing Owen, who claims to have no memory, despite clearly showing he remembers everyone and the competition. Chris and Chef Hatchet, watching from the plane, thank the Colonel for doing Owen's make-up job and mullet hairdo, while Duncan finally gets the aliens off Tyler and Alejandro and traps one into a cardboard box, confident.
Gwen brings Team Amazon the original box Team Chris Is Really Really Really Really Hot had found, which Courtney and Sierra object to. However, Heather tells them to "save it for first class" as they run out of the warehouse. Tyler, on the other hand, is too busy gloating to notice that Team Chris Is Really Really Really Really Hot is now on a mine field. Tyler is blown up and launched into the air, landing by Chris with the charred remains of the alien. When he lands, Tyler can only see hallucinations. Chris announces that the specimen is not alive. Team Amazon almost loses their box because Courtney trips Gwen, but Chris catches it and they win the challenge. In first class, Heather is surprised at Courtney's obsession with eliminating Gwen, noting that Courtney has replaced Izzy in terms of insanity. In the meantime, Gwen disappears to spy on the elimination ceremony, where Chris is explaining how Team Chris Is Really Really Really Really Hot failed due to their lack of teamwork. Tyler, now bandaged up due to his injuries from the mine explosion, is ecstatic due to thinking that Duncan is out, remembering his earlier discussion with Alejandro, only to discover that he's been voted off instead. Courtney protests at first, but when Tyler asks if there can be a re-vote, she angrily knocks a severely injured Tyler out of the plane. Courtney says she will have her revenge on Duncan and Gwen next. Since she said the key word "revenge", Owen is hypnotized and starts dancing again. Chris signs off the show while wondering whether or not Courtney will ever get her revenge on Gwen and Duncan.
Tyler is seen taking the Drop of Shame, saying, that he's sad about his elimination, though he becomes happy and says that this was his best season. He looks at the camera and tells Lindsay he is coming to see her, also asking whether she remembers him this time. After that, an alien is coming towards him. Tyler then says that it can't beat him alone. Though, a whole team of aliens appear and Tyler says that now, they can beat him. The camera zooms out, and he is then seen being zapped by the aliens in the sky.
- Chef Hatchet and Ezekiel appear; however, they do not speak, although Chef was heard agreeing with Chris.
- A robot speaks, but it is unknown who it is voiced by.
