context: In the future, on the planet Dorothy, a world dominated by canine humanoids, pompadour-wearing "Sweet" JP races in the planet's Yellowline car race, a final elimination race despite two interplanetary wars to the most popular race in the galaxy, the Redline. The crowd is watching the race on an outdoor giant monitor screen in the desert town of the Water Stop. His mechanic, Joshua "Frisbee" Flathead, is watching the televised race with a mafia boss. The gambling boss is concerned that JP might attempt to win the fixed race but Frisbee reassures him that JP needs bail bond funds from the pay-off. JP attempts to win anyway while Frisbee resorts to using a remote detonator transmitter hidden in the palm of his hand which the mob boss doesn't notice, causing JP's TransAM20000 to explode and making the 'Crab Sonoshee Sea' hovercraft piloted by female racer Sonoshee "Cherry Boy Hunter" McLaren the winner.
  While recuperating from the explosion in a planet Dorothy hospital Frisbee tells JP he's off the hook with his bondsman. JP initially turns down the money but a crowd of reporters storms the hospital room where JP learns that he has been voted by popular demand for the Redline following the dropout of two qualifiers due to the revelation of the race's location being Roboworld, a planet dominated by purist, militant zealot cyborgs whose President has threatened on interstellar television to hang all involved with the Redline mothership if it appears out of hyperspace over their planet with the race's hundreds of television satellites, exposing their secretive weapons build-up against treaty.
  Inside DEST Tower on Roboworld, the President asks Secretary of Defense Titan for a report about ships landing on Roboworld's moon, EUÐ¯PSS (pronounced Europass), a de-militarized zone that Roboworld signed away to refugees in the M-3 Nebula Federation, making it off limits to Roboworld troops. The President obtains a verbal oath from Colonel Volton to fight to the death to protect Roboworld and the M-3 Nebula.
  While the racers are staying on Europass before REDLINE under constant media coverage, Frisbee's alien junk dealer, Old Man Mole, wants to put weapons on the restored TransAM which JP refuses despite his competitors being armed. Old Man Mole also protests the presence of Frisbee on their team and his insistence on using a rare uncontrollable hyper-powered engine, but eventually gives in to JP's convincing.
  JP finds Sonoshee McLaren in the slow hours of the Oasis Restaurant. Shinkai, formerly of the Roboworld army, shows up at the Oasis when racer Little Deyzuna, a recently AWOL subordinate of Col. Volton, attacks Shinkai's partner, Trava. The Redline favorite, Machinehead, a tall menacing cyborg, appears and attacks Little Deyzuna, who is retrieved by Col. Volton. Machinehead confronts Volton for being in the de-militarized zone. Volton reminds the racer the Redline event will be repelled by the army and police before leaving the damaged restaurant.
  Fireworks celebrations and bookmaker agent desks break out on Roboworld despite the threats from the military and are raided by deadly android police robots. Miners on Roboworld use their power suits to sabotage the military base's power station while the Race Commission, which promotes gambling, hires Earth-native racing partners Lynchman and Johnny Boya to sabotage the Orbital Disintegration Cannon which Secretary Titan plans to destroy the Redline mothership with the instant it comes out of hyperspace.
  While in hyperspace, the Princess on the Redline ship from the planet Supergrass marks the course on a military base with a pair of scout vessels with the starting line to the north at the Knock-out Tower and the finish line to the south, east of DEST Tower. Unaware of the sabotage against the Orbital Disintegration Cannon the President realizes the racers are on the planet once it fails and sends his troops en masse at the racers. The President becomes increasingly desperate as the racers evade them and approach the mine-laden Zone XXXXXXX (pronounced "Seven X"), lair of a secret illegal biological weapon named Funky Boy which awakens from its stasis as the racers and the rebellious miners converge on it. With Funky Boy awakening and subsequent destruction of the base coinciding with the orbital cannon coming back online the President orders Funky Boy fired upon. The explosion takes out most of the racers while JP pushes to right his car off its side. Sonoshee, her vehicle ruined, agrees to ride with him to the finish line as Funky Boy regenerates but is taken out by Col. Volton, who dangerously merges physically with yet another bioweapon.
  Frisbee watches the race on several televisions parked atop a mesa in the mob boss's giant Cadillac hovercraft where he revives the same Yellowline deal. Frisbee however, refuses to detonate the explosive charge this time, wanting to see his friend win 'the big one' for just once. He is attacked by mobsters for his decision but is saved by Old Man Mole who discovered Frisbee's sabotage and shoots and kills the mob boss and his lackeys.
  As the race nears the finish line Machinehead and JP race to the southern finish line boosted by their rare Steamlight boosters. As they come to a desperate neck-and-neck finish a drunk Old Man Mole accidentally detonates Frisbee's remote detonator, propelling JP and Sonoshee towards the finish thrown from their vehicle. The boost is enough and JP wins by the length of his long pompadour. As the racers rest at the end of the race amidst the ruins of Roboworld, JP and Sonoshee float back down to the ground declaring their love for each other. The menacing cyborg, Machinehead, who vowed to win but comes in second sees the romance while his rage turns to laughter, happy with the outcome.
