Exhaustion becomes palpable as the chefs enter hour 13 of their 24-hour competition. Hosts Michael Symon and Esther Choi challenge them with the unenviable task of turning microwave meals into works of art, and that's the easy part! Guest judge Eric Adjepong will decide which of these chefs must clock out.

Michael Symon and Esther Choi begin the most devious shift of all as the chefs earn points during each challenge. They'll be tested in cooking, strategy and much more as judge Maneet Chauhan decides their fate just two shifts shy of a massive pay day. Then, Michael and Esther start hour 18 by testing the bruised, battered and exhausted chefs on their simplicity, one of the most difficult techniques to master. Judge Brooke Williamson decides which four chefs will receive a spot in the finale.
