"The battle of the sexes continues, yes?" Chef asks as he dismisses the realigned teams. Rock and Bonnie meet with their squads in the dorms. Julia promises to help Bonnie, even though she thinks Rock deserves to win.

Rock shows the guys the stations that he has broken down. They get to work cramming over the menu. Meanwhile, Bonnie reclines on the couch, talking to the women. Melissa is surprised that Bonnie doesn't have recipes ready yet. Bonnie knows this, and she is nervous.

As construction of the two dining rooms continues, Rock's blue team preps. Bonnie deals with Julia giving her attitude. It is three hours left to go until dinner service and the architect informs Bonnie that he has run out of wallpaper even though there are still walls left to cover. "I'm just trying to get through this without crying," Bonnie laments over the new roadblocks.

Rock tries to keep abreast of details in the kitchen, even if that means overseeing everything that Josh has to do. "I trust you," Rock says to Josh. "So trust yourself." Bonnie is finding that she has the same task with Melissa and needs to watch her every step.

Bonnie and Rock must run their dishes past Chef. He likes Bonnie's chévre salad with herbed breaded goat cheese appetizer, especially noting her roasted peppers. He commends the pasta and sauce in her signature fettuccini with sautéed Thai prawns dish, but stops on the fish part. "Melissa keeps overcooking my f***ing prawns," she says as an aside to the camera. Yet Chef is not impressed by her dessert of chocolate truffles because it's too small. He gives her advice to change it.

Chef praises Rock's entrée of pan-roasted prime rib eye with a morel mushroom sauce. Yet Chef is concerned that there's too much garlic in the jasmine rice underneath the crispy chicken and crab cake appetizer. Rock worries that one of his chefs has screwed up. Chef thinks the vanilla bean milk shake with double chocolate chunk cookies dessert tastes nice but is "clumsy." He thinks Rock should switch the drink to be served in a martini glass. "All of the things he suggested were fixable," Rock declares.

Chef feels that Bonnie's menu is elegant, vibrant, light, balanced, fragrant and dainty while Rock's menu is substantial, robust, rich and heavy. "But what they've both gotta do is drive that kitchen from the first table coming in," Chef notes.

With thirty minutes to go, workers scramble to get Rock's booths installed. Bonnie walks Chef through the concept of her dining room. He likes that there's no intimidation in the design and he can "relax right away." Chef lets her know that her hardwood floors could create a lot of noise. He commends her table set-up as "nice, clean, elegant." He describes it as a "neighborhood restaurant done with a little bit of panache." The décor turned out exactly the way Bonnie wanted it. Chef Ramsay calls Rock's dining room "elegant" and "rich and sumptuous." Rock is happy with Chef's approval, but he wants to focus on the food.

Chef calls the pair over for some final words of advice. He assures them that he will be watching everything in the kitchen. "Run it, or it runs you," he dictates. Then Chef gifts them with personalized master chef jackets. They are touched.

Right before opening, Rock and Bonnie rally their teams. Rock asks the guys to be honest about their times and to ask questions. Bonnie encourages high energy and requests they be honest if something messes up. Chef has Jean Phillipe open Hell's Kitchen. Rock and Bonnie call out the first orders to their staff. Chef sees that the Blue Kitchen is working well. When the women do not answer in the usual "Yes Chef," Bonnie becomes worried that her team isn't taking her seriously as a leader. She pushes them to work together.

Josh is on the app station, and Rock notices that he is burning the crab cakes. Rock rushes him and struggles to get Josh on track. In the Red Kitchen, Bonnie urges Jen to speak louder but Jen claims that she is. Then Julia says something to Bonnie, but Bonnie doesn't reply immediately to her and Julia feels like she is being ignored. Chef comments that no one is speaking to each other in the Red Kitchen and this has taken the energy right out of the service. Yet Bonnie still manages to get her appetizers out.

Chef catches Josh cooking six crab cakes, which is more than has been ordered. Chef has Rock do quality control because the crab cakes look dry. Rock encourages Josh not to "freak out." Yet everyone else's food is slowed down because of Josh.

Bonnie's team moves onto entrees. Melissa alerts Bonnie that there are only four orders left of the fettuccini pasta, and Bonnie asks why she wasn't told this sooner. "I'm sorry?" Melissa asks. Chef yells at Bonnie for not knowing how many portions she began with in the first place. She accepts responsibility for being under-prepped.

Josh still has trouble delivering food. Chef pulls Rock backstage to warn him that Josh is sinking his ship. Rock responds by prodding Josh to "get it together." Rock refuses to let anyone interfere with his dream. He is forced to pull Josh off the app station when he burns more crab cakes. Rock swaps Vinnie in for Josh. Chef is pleased that Rock made this move. Although Vinnie isn't prepared for the fish, he manages to get some dishes out.

The Red Kitchen starts to communicate. Yet Melissa brings news that they have run out of prawns. Then, a customer complains that her pasta dish was served cold and the prawn is undercooked. Jean Phillipe brings it back, but Bonnie cannot replace the dish because she has run out of prawns. Bonnie tries rallying her cooks. "Just be happy I'm getting you your food," Julia says.

Three hours into the dinner service, Rock's team has found its rhythm. While Bonnie pushes her team to get their desserts out, Julia argues with her. Julia claims she wasn't ready to wrap up the goat cheese at the moment Bonnie asked her to. Yet Bonnie persists, angry that she is being defied. "It was just blatant that she didn't want to listen to me," Bonnie says to the camera. She has to explain to Chef that she couldn't get someone in her kitchen to obey her. Both Bonnie and Rock struggle to get out their last desserts.

"Josh really, really screwed up," Rock sighs after the service is completed. "It definitely hurt my chances for winning." Bonnie thanks all the women for their help. Julia congratulates her on a great job. Rock's wife and kids come to greet him over the counter. It gives him a big boost.

When the restaurant is closed, Chef assembles the teams. Rock admits that, if he could turn back the clock he would have chosen Jen first because she has impressed him the most. Rock also confesses that he would not have put Josh on his team. Bonnie says that she would have spent more time checking portions and food to prevent running out. "Well done to you both," Chef says, pointing out that it's the strongest he's seen them. They completed a fully-booked service.

It's a tough decision for Chef because he thinks that both displayed leadership qualities. He's going to review the customer comment cards before appointing the winner. Bonnie and Rock say goodbye to their teammates and retreat back to the dorm. When alone, Rock and Bonnie hug each other and bemoan the stress of the night. They are proud that neither of them gave up but they are physically exhausted.

After studying the customer cards, Chef Ramsay meets with the two finalists in his office. He compliments Bonnie's assertiveness and says that she has surprised him the most. Then he calls Rock "rock solid" and remarks that there's safety in having him run a kitchen.

Chef invites them to stand in front of their respective doors. Only the winner's door will open. Bonnie and Rock grasp the handles. Rock's door opens. He enters to Hell's Kitchen where his family and the other chefs are waiting with applause. Rock starts to cry. "Thank God! I just won!" he exclaims. Bonnie is pleased for him and thinks Chef made the right decision. She is sure the right opportunity will find her.

"Rock deserved to win Hell's Kitchen because he's a very confident cook and he has become a really good leader," Chef says. As confetti pours throughout the restaurant and cheers go out, Chef makes a champagne toast to him. Rock hugs his wife, and Chef sprays champagne on everyone during the celebration.
