Olympic athletes Maurice Greene, Natalie Coughlin and Danell Leyva help Ramsay lead a 3K race, with the red and blue teams racing to prepare lunch for the runners; communication issues lead to fights during the dinner service.

Twenty aspiring restaurateurs present their signature dishes to Ramsay -- and an audience -- in Las Vegas; while the challenge winners earn a night out on the town, the losers must head back to Los Angeles on a school bus.

The contestants enter an animal pen to determine which type of protein they will cook in the team challenge; during dinner service, the contestants must impress chef Ramsay's family.

During the team challenge all five senses are put to the test. Chef Ramsay announces a reward that pits chef against chef, and with the stakes higher than ever you wont believe what one chef will do to save themselves from elimination.

The contestants arrive at the dorms; Ramsay sends contestants out of the kitchen after a rocky first dinner service.

Chef Martin Yan judges six Chinese dishes created by the remaining contestants; during dinner service, one team disappoints a VIP guest; a contestant is eliminated.
