Racer and viral video star Ken Block finishes his latest video project, "Climbkhana," while beginning preparations for his largest video project yet, "GymkhanaTEN"; with extreme altitude and wild weather, it might be his most difficult shoot yet.

After the incredible success of Climbkhana, the stakes are high for the first shoot of GymkhanaTEN. The first segment kicks off the yearlong project, so Ken, Brian and the others bring the game-changing Ford Mustang Hoonicorn V2 to Detroit.

With Detroit in the bag, the team separates while Brian continues preparing GymkhanaTEN. Elsewhere, Ken flies halfway around the globe to Lohéac, France, to compete in the World Rallycross Championship against some of the world's best drivers.

After an unexpected week in France, Ken heads to Los Angeles, where he and the team ready their newest contraption, a 1991 Ford Escort Cosworth RS on steel rims; they hope the steel bands will throw sparks everywhere for a wild-looking segment.

With Los Angeles now behind them, the team splinters and communication grinds to a halt. Meanwhile, Ken heads back to WorldRX, where he struggles with a difficult decision and Brian is all the way across the world in Sweden.

On an ice lake in far north Sweden, Ken, Brian and the crew regroup and focus on the task at hand. Plus, with the craziest filming conditions the team has ever experienced, the crew knows it is in for a challenge.
