Gordon Ramsay is pushed to his limits in the Smoky Mountains. In his quest to unearth the region's culinary secrets, Gordon must rappel down a treacherous waterfall, kayak through raging rapids, and trek deep into the forest, attempting to find the most delicious ingredients in this magnificent mountain range. His culinary rival at the big cook is chef William Dissen, named one of America's "Most Sustainable Chefs," who knows these mountains, rivers and forests like the back of his hand.

Gordon Ramsay discovers the culinary secrets of the country's legendary Oaxaca region, where mole reigns supreme. In addition to learning to make the storied chocolate- and chili-infused sauce, Gordon must rappel down a cliff in search of delicious butter worms, harvest the honey sacs from burrowing ants and fend off angry wasps in search of their coveted larva. In his effort to measure up to acclaimed Mexico City chef Gabriela Cámara, he will also engage in the punishing physical process of harvesting agave plants to make mescal.
