Chef Ramsay puts the contestants through a physical challenge involving lobsters; while the challenge winners enjoy a day on a yacht, the losing team must clean hundreds of pounds of fish; Ramsay is disappointed by a disorganized 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 arrive at the dorms; Ramsay sends contestants out of the kitchen after a rocky first dinner service.

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.

Ramsay makes a decision that changes the competition; two chefs work as servers during the dinner service; each team nominates two contestants to be put up for elimination.

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.
