The four remaining teams pan for gold to earn their seed money, and some teams gain a clear head start on shopping and selling. Meanwhile, extreme cold and winds continue to challenge everyone. Tyler Florence issues a challenge to the teams to use a quintessential Alaskan ingredient -- crab -- to create a special dish for their menu, and the team that sells the most will win an extra $500 in their till.

In the wilds of Alaska, seven aspiring food truck teams kick off the biggest, boldest season of the Great Food Truck Race. On Flattop Mountain overlooking Anchorage, Tyler Florence welcomes the teams to the competition. They have to break the keys to their food trucks out of 200-pound blocks of ice, and that's only the beginning of their adventure. They won't just be battling each other -- they will be battling the elements as they compete to see who can prep and sell the most food and who will say goodbye to their food truck dreams forever.

The five food truck teams are tested as they go deep-sea fishing in order to earn their seed money from Tyler Florence. The Alaskan elements are taking their toll not just on the teams but also on the trucks. One truck breaks down on the side of the road, and several teams underestimate the huge demand for their food in Homer, struggling to meet demand and keep their kitchens stocked. A surprise judge visits all the teams and tastes their dishes, and his favorite dish will win its creators a huge advantage -- immunity from elimination!

Tyler Florence challenges the six remaining food truck teams to practice their survival skills by starting a fire to make delicious s'mores, and the judges for the taste test are the other teams! Because of its long daylight hours in the summer, Palmer, Alaska, is home to some of the largest vegetables in the world. The teams are tasked with creating dishes using some of Palmer's most famous vegetables, but the obstacles mount as the teams start to sell amid short daylight hours, raging winds and blistering cold.

The final two teams meet up with Tyler Florence and go head-to-head in rugged Fairbanks, Alaska, where intense challenges and tough sell days test both food trucks like never before. With unparalleled grit and determination, one team will be named the champion and win the grand prize of $50,000, and one team will leave Alaska with only dashed food truck dreams.

Three teams battle it out in the coldest and most remote location to date -- Talkeetna, Alaska. In a scavenger hunt for a local favorite, chaga mushrooms, the competitors strategize to win varying amounts of money to spend on supplies. Tyler Florence is forced to give some harsh feedback and issues a challenge to help them turn things around. The food truck teams can almost taste victory as elimination decides the final two teams of the competition.
