With some of the most challenging terrain on earth being in the United States, two crews of world-class mountain bikers are sent out to create their own. The first crew travels from the Black Hills of South Dakota to Lake Alcova, Wyoming exploring exotic dirt terrain. Meanwhile crew number two tours Northern New England on motorcycles to find challenging dirt jumps near Laconia, New Hampshire. Both crews learn that if you search hard enough, what's born in the USA is the Ultimate Rush.
