Chefs often describe their jobs as being 24/7/365 in the eat-or-be-eaten restaurant industry, but no cooking competition has ever captured that knock-down, drag-out intensity -- until now! Michael Symon and Esther Choi host the world's toughest cooking competition that's part culinary marathon and part social experiment where 24 chefs take on 24 challenges over 24 real, nonstop hours. The challenges are divided into eight shifts, each testing a different culinary skill like speed, resourcefulness, artistry and adaptability, which these brave chefs must try to conquer as the lowest scoring chefs get eliminated. The 24-hour clock never stops until there is only one true master left to take home their biggest single-day payday ever.

After working with the world's top chefs, Selena Gomez is raising the stakes! She heads out to work in Los Angeles' hottest restaurants, where she'll be put through her paces and have to learn fast to create a dish good enough for the restaurant's menu!

Brave and talented chefs attempt to take down Iron Chef Alex Guarnaschelli, the most feared and accomplished competition cook in America. Chef Alex goes up against three chefs in two rounds of cooking, and anyone -- even Alex -- can be sent home after a blind tasting by the judges. Each chef hails from a different state, but they all share the same culinary specialty and drive to beat Alex for ultimate bragging rights and their share of $15,000.
