The last four chefs retreat to the dorms after elimination. Christina is not happy that Jen's still a contender. Jen wonders whether she should have tried harder to make friends. She tells Christina that she wasn't offended by what was said at elimination. "We need to get rid of Jen," Corey laments in secret to Christina and Petrozza.
The next day, Chef announces that they are going to face "the mother of all challenges." Their 80 customers for lunch will determine who wins. They have one hour to prepare whatever they want. Everyone seems to be calmly working, but Corey is unusually panicked.
Jen describes Petrozza's Monte Cristo sandwich as "a heart attack dipped in a stroke with a side of cardiac arrest." Corey can barely get her food on the table in time. Jean-Phillipe opens the door and 80 pregnant women walk in. Corey has to go back and prepare more when she runs out. She strands some very hungry diners. Christina steps in and offers up her dishes to those who are waiting.
Petrozza wins some of the moms-to-be over by telling them he's a dad. Chef goes into the kitchen to berate Corey, who's still chopping. The patrons pick their favorites. Chef announces that Corey is in fourth place and Jen is in third. Although the voting was within two votes, the winner is Christina.
For her prize, Christina gets to go shopping with Chef Ramsay in Beverly Hills. She runs off excitedly to get changed. The losers have to clean the dining room and polish the silverware. Corey is massively jealous. She thinks Christina has no style. The owner of the boutique and Chef Ramsay help Christina choose outfits to buy. Returning to the restaurant, Christina shows off her new clothes to her competitors. The other girls are boiling mad.
Petrozza, Jen and Corey start prepping for dinner. Christina comes down from the dorm and repeatedly asks what she can do to help. No one answers.
The doors to Hell's Kitchen open for dinner. Jen gets down to business, calling out her times to the window. Chef commends Corey on her scallops and deems Jen's risotto "stunning." Their appetizers continue to fly out of the kitchen, until Jen's dish suddenly becomes "mush." Chef yells that her spoon is crushing the rice and that she's not paying attention. She starts to fall apart, but recovers to deliver a dish to his liking.
Christina gives Chef Ramsay her pot and he burns his hand on the handle. He chews her out for not warning him. However, she does it again and he is injured. "Wake up!" he screams.
Corey asks Jen to cook some eggs for her, but Jen refuses. Christina helps out instead. Jen stands there stirring one pan while the other two girls run around frantically. Yet when Chef asks, Jen gladly offers to cook the eggs.
Corey tries to get out her fish, but it is taking longer than expected. She sends it out even though she knows it is undercooked. Chef doesn't notice, but the customers do and send it back. Corey has to start over. Petrozza can only laugh.
Chef notes that Petrozza's section is a complete mess. At least he's getting his meat dishes out properly. An hour and a half into service and they serve their last desserts. The chefs make record time completing the service.
Chef Ramsay surprisingly gives them all high fives for an extraordinary service. He commends them for overcoming some sticky situations like a team. Chef asks them to come to a consensus about which two should be put up for elimination.
They decide to each anonymously write down two names on slips of paper and count up the tallies. As she's counting the ballots, Corey realizes that someone has written down Christina's name twice. She knows it is Jen, but Jen feigns innocence. Jen thinks everyone is threatened by her. The other three don't know how to bring Jen down. They try to figure out who the second person should be to stand up with Jen at the chopping block so that they can get rid of her.
Later, they march down to the dining room. Chef thanks them for a good night's service, but he has to send someone home. Christina tells him that their first pick is Jen because she lacks teamwork. The other nominee is, shockingly, Corey.
Corey pleads that she is a valuable asset to the team and has always bounced back. Jen says that her passion in the kitchen is clear. Corey claims she is more honest than Jen and more committed to the team. Chef Ramsay ultimately chooses Jen to go home, and encourages her to keep going in her career. She was not consistent in her attitude.
The other three are so relieved, not only because they got to stay but because Jen is gone.
