After seeing the devastation of fires in California and meeting the first responders who put their lives on the line to save people and communities there, Guy Fieri has decided to bring some of those firefighting first responders to Flavortown for a friendly culinary competition. They're challenged to make a firehouse favorite in the first round, and the second round is full of scorching-hot culinary combat as they make a spicy family meal. When the smoke clears, one firefighter will be left standing with the chance to win $20,000.

Guy Fieri brings back three pairs of rival chefs who previously faced off one-on-one. First, two budget-brawlers settle the score in a round that has them shopping for ingredients under $5 for their family dinners. Next, a couple of food scientists face-off in a game that forces them to shop for their dishes in either the odd or even aisles. The final round brings back two Flavortown all-stars for an exact recreation of their first matchup. The winner of each round wins ultimate bragging rights and a guaranteed $5,000.
