| After winning a practice race, Speed Racer is offered a driver position on the factory racing team owned by the company who employs his father, Pops Racer. Speed declines the offer because Pops is opposed to him becoming a professional driver. Meanwhile, Pops resigns his engineering job with the factory after an argument with chief engineer Mr. Van Ruffle during a board meeting where the board rejects his plans for improving the Mach 5. While Speed drives Pops home, a gang of thugs on racing bikes snatch Pop's briefcase with the plans. Speed jumps from bike to bike trying to get the plans back, but fails. He spots Trixie overhead in the helicopter and radios her to pursue the thug with the plans. She buzzes him, forcing him to drop the briefcase and crash off the edge of the mountain road. Speed recovers the briefcase. That night at the Racer home, Pops plans what he is going to do now that he has no job. He decides to remodel the Mach 5 himself, but does not know how he will come up with the money that he will need. Later, at Van Ruffle's house, the thugs explain how they failed to get the plans. Ace Deucey crashes the meeting and makes a deal with Van Ruffle to steal the plans for $5,000. The next day Speed visits Sparky to let him know he is selling the Mach 5 to help raise the money Pops needs to build the new engine. Sparky suggests that Speed should enter the Sword Mountain Race for a $5,000 prize, and Speed decides to enter the race. Meanwhile, Ace pays a visit to Pops at the Racer home. Ace pulls a gun and starts searching for the plans but does not find them. Speed arrives and interrupts him. Deucey leaves, vowing to come back for the plans. Deucey did not find the plans because Pops has hidden the plans on a spare windshield using invisible ink. Taking out the Mach 5 for a road test, a dirty racer named Skull Duggery rams the car, causing Speed to throw a wheel and crash. Back at the garage, the car is repaired, but they need a new windshield. Spritle Racer and Chim Chim walk in with Pop's windshield. Ace finds out that the plans are on the windshield and goes after the Mach 5. He and his gang start to wipe out the other cars in the race. They catch up to Speed and try to run him off the road. Speed guesses where the plans are hidden and avoids getting his tires shredded by Ace's gang by hitting the auto jack button. The Mach 5 is propelled over the guardrail and down an embankment. |||

| Speed reviews all the special features of the Mach 5. Resuming the Sword Mountain Race, Ace Deucey and his gang watch Speed race down the embankment and escape. Speed races to catch up to the rest of the racers and eventually takes the lead from Duggery, However, he soon encounters Ace and his gang racing towards him from the opposite direction. He detours off the race course and uses the rotary saws to cut a path through the overgrown terrain. Duggery follows Speed, with Ace and his gang close behind. Trixie creates a distraction by bombing the gang with smoke-filled flares from her plane. Duggery makes a decision to take a shortcut at a crossroad. Speed realizes Duggery is headed to a very dangerous volcano and follows him. Meanwhile, Trixie continues to distract Ace and his gang with smoke bombs, but they shoot and damage her plane, forcing Trixie to bail out. At the volcano's edge, Duggery is thrown from his car and is left dangling from a rock in the crater. Speed falls into the crater while looking for Duggery and lands on a ledge just above Duggery. Speed saves Duggery just as the rock gives way. They climb out of the crater, only to find Ace and his gang have arrived and have Trixie as a hostage. Ace orders his gang to finish off Speed and Ace. Just as the gang is about to finish off Speed, Spritle and Chim Chim start shooting rocks at Ace's gang from the trunk of the Mach 5 with a slingshot. Speed and Duggery take advantage of the distraction to attack the thugs, but Ace escapes in the Mach 5. Speed races in pursuit using Ace's car, but it cannot catch the Mach 5. Ace does not know how to control the special features of the Mach 5 and ends up causing the car to slow down, giving Speed a chance to catch up to him. Speed leaps into the Mach 5 and wrestles with Ace. At the last second, Speed is able to throw Ace from the car and regain control of the Mach 5 before it drives off the edge of a cliff. Speed thinks he is safe and has a moment to rest, but Ace reappears and prepares to kill Speed. Speed smashes the windshield of the Mach 5 with his helmet and leaps at Ace, throwing him over the side of the cliff. Speed watches Duggery race past in his car and resumes the race. Speed passes Duggery and wins the race, but the results of the race are nullified due to the interference of Ace and his gang. |||

Now, Pops blows a gasket and has a remembrance of the time his oldest son, Rex, entered and joined a race without any permission from him. Almost close to victory, Rex crashed the car that was built for him by Pops. Although Rex was not injured, Pops forbids his son to drive again due to Rex's lack of experience. Rex made a vow to never return home. The Alpha Team is on a conference, discussing many cheating ways to win the race. Mr. Wiley suggests Mr. Fixer and the Alpha Team driver Zoomer Slick to pull the dirty tricks first. With determination to beat the Masked Racer, Speed sneaks out in the middle of the night and goes to the track. Even with the heavy rains, Speed is not soaked. Out of nowhere, the Masked Racer warns Speed to stay out of the Trans-Country Race. He declines and says he wants to beat him and the only way to do it is to race blindly into the night.

At the racetrack, Speed receives an invitation to the Fire Festival Race. Speed finds this peculiar because Kapedapek does not have a racetrack and Kabala has been missing for a long time. Nevertheless, Speed and company arrive in Kapedapek. They spot Racer X, who was also invited. That night Chief Zuma lets it be known that "the winner of the race will be bridegroom" to his granddaughter, Princess Silvana. He points out Speed as the probable winner.

Later, Mr. Kadar captures the Princess and demands to know where the country's treasure is hidden. Speed comes to her rescue. The next day, the racers and their cars are carried by raft to a secret entrance in a volcanic mountain. The racers drive through a tunnel to an ancient city with bejeweled statues.

To return Kabala's kindness, Racer X disguised himself as Kabala to protect the Kapedapekan treasure. Kadar and his men succumb to the lava flow. Speed, followed by Racer X, exits the mountain just as it erupts and seals the split. Although Speed won the race, the Chief will not concede.
