The judges and dinner guests will vote on the dishes, leaving the bottom two celebrities to compete in a sudden death challenge. At the end of the day, one celebrity is eliminated from the competition.
Team Rachael and Team Guy take to farming in this episode at Underwood Family Farm, as they gather produce and create fresh, farm-to-table dishes for the staff, family, and friends. It's a good, old-fashioned feast served family-style in the middle of a walnut grove. Underwood Family and their guests will vote on which team wins, with the bottom two celebrities on the losing team going head-to-head in a sudden death challenge to determine which one goes home.
The teams must revamp the menu of Mel's Diner on Sunset Boulevard by putting a new and unique spin on three classic diner foods. They will cook their dishes and then, in old-school, diner fashion, dress the part with outfits, roller skates, paper hats and hairnets to serve to customers inside the restaurant and in their cars. In the end, the customers decide the winners of the competition, leaving two celebrities to compete in the elimination challenge.
It's a battle of the sexes as the teams must throw a birthday party for one lucky girl and boy.

Rico Rodriguez from Modern Family will help judge the celebrities, with the bottom two battling it out in a sudden death elimination.
With four celebrities remaining, Rachael and Guy explain the penultimate challenge, as two food trucks roll into the parking lot, one branded Team Rachael and the other Team Guy. The teams must choose a theme and come up with menu items for their truck. Season one winner Lou Diamond Phillips will guest judge a surprising double elimination to determine which celebrities go on to the finale.
