In the new episode "Winners Mystery Box – Spirit of Vegas," the chefs face their first mystery box challenge of the season, presented to them by returning Season 7 winner Shaun O'Neale. The chefs have just 60 minutes to cook three identical dishes using the spirits their mystery box contains. How well they perform may determine whether they win immunity or suffer elimination. Host Gordon Ramsay, Aarón Sánchez and Joe Bastianich are the judges.
