Welcome to beautiful Nova Honda, the racing capital of the world. It is the home of the prestigious World Grand Prix, the illegal street race The Cannonball, and the racer caught between both of them, Domino Swift. Domino is one of the best racers on any circuit. By day, she competes for fame and fortune in the WGP. By night, she cracks heads of rival gangs in brutal bike wars to gain possession of a rare, valuable contraband: an engine-boosting machine stimulant known as Crush.
