The two teams are combined to create a single team. Each chef is asked to create a dish designed specifically to please Chef Ramsay centered around a single main ingredient. The new unified team struggles to complete its first service together. Two chefs scheme together to plot another’s downfall. The winner of the challenge is invited on a very special trip — a visit to Vegas and a meeting with Rock Harper, the winner of the show’s third season. The show’s medics are put the test when things once again get a little too hot. One chef goes ballistic when the pressure of the evening’s dinner service gets to be just a bit too much.
