In the supersized season premiere, hosts Michael Symon and Esther Choi welcome 24 of the country's best chefs to the most intense cooking competition ever devised: 24 challenges in 24 non-stop hours. In the first shift, the chefs learn this season is completely different from previous ones - from picking which challenge they do to a completely new way of judging, this competition will test the chefs in unexpected and devious ways. If they can impress guest judge Jet Tila in the strategy skills round, they will have a chance to continue the longest day of their professional lives. 

Fatigue is setting in for the 12 remaining chefs as co-hosts Michael Symon and Esther Choi challenge them to craft a black-tie entree in 90 minutes using only five ingredients. The chefs will have to choose their fate as a triple elimination looms. The nine chefs that impress judge Eric Adjepong will survive, and the ones that don't will clock out.
