Martha Stewart is at it again, revealing a showstopping twist in the Martha Rules tournament: There's only one spot in the dessert round because a mysterious fifth chef is waiting in the wings to compete against whomever makes it that far. The four competing chefs can be eliminated at any time, for any reason, and the mood is tense as they dig into the appetizer basket, which includes a beautiful cake and a bitter beverage. The entree basket contains a hot dog with a long history in Maine, the site of the competition. The mystery competitor steps up for the sudden-death dessert round, and only one chef advances to the $50,000 finale.
