Cyber mechanic Nova lives a perfect life after growing up poor and alone in the big city. She has found happiness with her girlfriend Cherry, and Cherrys family has all but adopted her. But when Nova and Cherry witness the death of Cherrys family at the hands of a masked assassin, their world is turned upside down and they vow to get revenge. Soon, Nova discovers that the murders are tied to an underground racing ring run by an organization called Checkmate and their ruthless leader, Queen. Determined to uncover the identity of the assassin, Nova enters the ring with a pair of high-tech skates, while Queen watches her every move from afar.
