Seven incredible food truck teams assemble at Fisherman's Wharf in the food capital of the United States, San Francisco, to do battle as Great Food Truck Race All-Stars. Host Tyler Florence challenges the food trucks -- Aloha Plate, The Middle Feast, Seoul Sausage, The Lime Truck, Waffle Love, NOLA Creations and Mystikka Masala -- to complete a special bread bowl challenge to uncover the keys to their trucks. The teams head out to shop and sell for the first day of the intense competition. When these best-of-the-best teams face off, a small decision has huge consequences and sends one all-star team home.

In Napa Valley, Calif., the six remaining food truck teams go head-to-head in a grape-stomping competition with a unique prize. Host Tyler Florence challenges them to incorporate red wine in a dish for a taste test he judges, and he forces the teams to get back to their roots and compete for sales the old-fashioned way. After two days of selling, one team has a stellar sales total, and one truck must close its doors for good.

As they gather in a forest of California redwoods, host Tyler Florence tells the five remaining food truck teams that they need to forage for ingredients to make a tasty treat. Surprise judges determine whose creation wins the prize. Using the ingredients from the challenge, the teams must make a dish with the power to keep them in the race, but for one team, it's the end of the road.

The four remaining food truck teams meet host Tyler Florence on the beach to create their own signature beachside snack. Judges award $300 to the team with the most-delicious beach bite, and the team that sells the most treats earns $300 as well. Rivalries grow, and the sales competition is fierce among the final four teams, but a mistake in strategy leads one all-star team to give up its dreams of winning the title.
