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.

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.

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.
