It is the eve of the last dinner service in Hell's Kitchen, and a group of former contestants has been brought in to assist finalists Ja'Nel and Mary in the season conclusion. Although Ja'Nel briefly considers making a team member trade with Mary, she decides to keep her group intact.
The next morning, Mary, Ja'Nel and their brigades are focused on prepping their menus and getting sample dishes ready for Chef Ramsay's input and approval. The ever-confident Zach says he and Ray are the secret weapons that are going to take Ja'Nel to victory - but Susan is concerned that they're bad apples who are going to spoil the whole bunch. In the Red Kitchen, Mary worries that Dan's questionable attitude and skill level are going to slow down her team.
With 15 minutes remaining until Chef Ramsay arrives, Mary and Ja'Nel push their teams to complete their dishes. Although Dan isn't exactly being cooperative, Mary decides to keep forging ahead but will keep an eye on him at dinner service.
When Ja'Nel presents her menu to Chef Ramsay, she explains that she's taken a few Southern dishes with classic flavors and added some elements to elevate them a bit. He praises her BLT salad, roasted veal cheeks and oven-roasted chicken. He also compliments Mary on her sweet potato gnocchi, Chilean sea bass and short rib tortellini.
Before the guests arrive, Chef Ramsay gathers the entire group for a pep talk. He tells them there will be two VIP tables for the first time in a Hell's Kitchen finale. Ja'Nel will be serving actor Anthony Anderson, and Mary will welcome both actress Kat Graham and skateboard legend Tony Hawk.
As the doors to the restaurant open, Mary and Ja'Nel prepare for their final head-to-head battle. In the Blue Kitchen, Ja'Nel gets her team up and running with some extra support from Cyndi. Over on Mary's side, she's counting on Jon on fish and Nedra on appetizers to get off to a strong start.
On the Red Team, Mary is disturbed that Nedra doesn't taste her salad and is slow and noncommunicative. The head chef even goes as far as threatening to throw Nedra out of the kitchen.
Meanwhile, in the Blue Kitchen, Ray slows down the team when he fails to deliver a salad to Ja'Nel's standards. But despite waiting for their food, the diners are pleased with the final outcome.
After a bit of a slipup on scallops, the Red Kitchen moves on to entr?es. Mary's team kicks into high gear to push plates out to her guests, but Dan has to refire his cold and undercooked meat. After multiple attempts to get him on track, Mary finally throws him out of the kitchen.
Hoping that Nedra will quickly rectify the problem on the meat station, Mary sends the completed dishes from that table's order out to the hungry diners. But Nedra soon discovers that Dan has now overcooked almost all of the steaks. She finally finds a perfectly prepared piece and completes the ticket.
In the meantime, the Blue Kitchen has completely fallen apart over a lack of communication, but Ja'Nel manages to take control and rally back.
With dinner service complete, Chef Ramsay must make a difficult decision. In his office, he tells them Mary and Ja'Nel to step up to a set of doors. The contestant whose door opens will win the Hell's Kitchen competition to become the Head Chef at Gordon Ramsay Pub & Grill at Caesars Palace in Las Vegas, along with a salary of $250,000.
In the end, Ja'Nel emerges to a waiting crowd of friends, family and former competitors to celebrate her victory.
