JP finds Sonoshee in a restaurant on the moon, where many of the racers are converging. Old Man Mole protests the presence of Frisbee on their team, and Frisbee’s insistence on using a rare uncontrollable hyper-powered engine, but eventually gives in to JP's convincing. There, JP tries to sign his alien junk dealer Old Man Mole onto his team. The racers prepare for Redline by camping out on EUЯPSS, a demilitarized moon of Roboworld occupied by refugees in the M-3 Nebula Federation. 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 on Roboworld - a planet dominated by militant zealot cyborgs whose President has threatened on to hang all involved with the Redline mothership if it appears out of hyperspace over their planet. While recuperating from the explosion in a hospital, Frisbee tells JP he's off the hook with his bondsman. When JP, who was supposed to come in 2nd place, attempts to win anyway, Frisbee resorts to remotely detonating an explosive hidden under JP's TransAM20000, thereby making Sonoshee 'Cherry Boy Hunter' McLaren the final winner. JP's alien mechanic, Frisbee, watches the televised race along with a mafia boss, with whom they have fixed the race. On the planet Dorothy, 'Sweet' JP races in the Yellowline car race, the final elimination race to the most popular race in the galaxy, the Redline. It saw greater success following its home release, and is considered a cult film.

It premiered at the Locarno International Film Festival on August 14, 2009, and was theatrically released in Japan on Octoby Tohokushinsha Film. The film was in production for seven years, and used over 100,000 hand-drawn frames.
