For the Quickfire Challenge, Padma and guest judge Chef Michael Cimarusti challenge the chefs to cook dishes using ingredients corresponding to the element of their zodiac sign – earth, air, fire or water. The bottom two chefs square off in a Sudden Death Quickfire, where one chef will be eliminated immediately. Later, returning guest judge Graham Elliot splits the chefs into teams to throw a pirate-themed party in honor of Blackbeard. They'll have to race through the stormed-out streets of Charleston to collect their ingredients on a treasure hunt. After service, the chef with the worst dish on the losing team will be forced to walk the plank.
