The crew head back to the Utah birthplace of Nitro Circus, using the familiar rugged terrain to ride, race and wreck everything they can get their hands on. They redefine the ancient Roman chariot race with a new kind of horse-power. Then they handcraft their own motor homes to race on a figure-eight track and Streetbike Tommy crashes a Rock Crawler. Basically the cast creates some homecoming mayhem, Nitro-style.
