Scenes from the first act of the Nuclear Cowbowz performance at the arena. The show consist of FMX (freestyle motocross) tribes, the Soldiers of Havoc and the Metal Mulisha performing tricks in the supposed war torn city of Los Angeles, during the year 2150. The tale unfolds as the two tribes survival is threatened and besieged by an evil force, The Tempest and her Cyborg Army. Catapulted into the fray are the Nuclear Cowgirlz whose allegiance to their tribes only intensifies the Tempest's rage, wanting to destroy the Nuclear Cowboyz. The Soldiers of Havoc and the Metal Mulisha's battle is fought through freestyle stunts, combined with pyrotechnic and laser displays synchronized to heavy metal, rock alternative and electronic dubstep music.
