Plot: Reigning champs TEAM ZERO return to make history and defend their 2004 KOTR title from the superpowers of FLIP, HABITAT and ELEMENT. Four killer teams have two weeks to make their way across America skating, filming, competing and earning points by performing tricks in "the book," completing challenges in certain cities, doing other wacky challenges (like skating naked), picking up their "mystery guest" and battling it out with their film and video footage to do the highest, longest and gnarliest trick!
