This episode starts with Speed and Pops putting the finishing touches on a mini racer which the Kingdom of Sakkarin asked Pops to build for the Baby Grand Prix. The race will be held in celebration of the coronation of Prince Jam. Spritle wants to race in the Baby Grand Prix. He can't because the race is for 8 to 13 year olds, and he's only 7 years, 11 months, 23 days and 8 hours. To make matters worse, there won't be enough room to take him on the trip. This time, Speed flies on a 727 with some very large portholes. On the drive through Sakkarin, one of the suitcases falls off the trailer. Inside are Spritle and Chim Chim. Their first encounter is with a snake charmer's cobra. The palace in Sakkarin bears a striking resemblance to the Taj Mahal. Pops, when addressing the king, sounds so formal that he sounds ridiculous. He even addresses the king as, ""your royal highness majesty."" Trixie mistakes a really goofy looking royal person for Prince Jam, but it is really his cousin Prince Su

Speed Racer, his girlfriend Trixie and all the gang are in a desperate race to save hundreds of lives from the evil clutches of The Car Hater.

Speed gets chased to the edge of a cliff. The gorillas throw boulders at him and one knocks him off the cliff. General Smasher, who is watching Speed on the monitors is happy to be rid of ""that nosy young man"" once and for all. Smasher resembles Hitler, another fun-loving character from the 1940s. In order to secure Professor Carnivoré's cooperation, Smasher leads him into a room where he meets a former colleague, Professor Loon. Professor Loon shows off a giant gorilla. The gorilla often bites through the chains and escapes. Loon is summoned to the command post because the Mach Five is approaching the island. As the Mach Five approaches the island, a door opens underwater and the car is sucked inside. As Trixie and Spritle reach the end of a long tunnel, tanks are waiting for them. The tanks chase the Mach Five and Trixie's driving skills, which are at least as good as her flying skills, pan out and the car crashes. They are captured for Professor Loon's experiments.

Speed is competing in the first stage of the Sahara Race. He witnesses a man being buzzed by an airplane, registration R3513K. He uses the cutters to saw the tail off of the plane. The man is Dr. Digger O. Bone, an archaeologist. The gunman inside the aircraft tries to take one last shot at Dr. Bone but he collapses in the sand. Dr. Bone goes on to explain that the previous spring his daughter, Calcia, came over with his assistant, Splint Femur, to examine some of the Egyptian ruins. Dr. Bone gives Speed a photograph of the two. Femur claimed to have found Cleopatra's treasure. Dr. Bone scrawls the letters ""STFT"" in the sand before he dies. After doing some extensive research in the library, probably the one in Alexandria, Speed and Trixie figger out the mysterious code. The ""S"" stands for the ruins of Saqqara, which are on the banks of the Nile. The ""T"" means the ruins of Tamalamal and the other ""T"" stands for Tutankhamen. The ""F"" remains unexplained. Speed decides to drop out of the

As Speed continues to get shot at on his way to the top of the pyramid, he sees his life flash before his eyes. He takes advantage of the opportunity to recap the story. Speed throws the homing robot at the airplane. The rope which is attached gets tangled in the propeller, causing the plane to crash. Meanwhile, Trixie is being lowered into the flames. Femur uses her as an example to encourage obedience among the slaves. Speed, realizing he is running out of time, attaches the statue to the homing robot, and sends it on its way. The statue arrives just as the shadow reaches the eye, but Femur adds a new rule, Speed had to arrive in person with the statue. Speed arrives shortly. Calcia (Cleopatra) decides to spare Speed and Trixie, but puts them into service in her slave corps. Spritle is heard announcing the presence of the queen. Calcia moves the treasure hunt to the ceremonial house built by Cleopatra's father, Petranius XIII. Obviously, Calcia is not the student of Egyptian history

Luckily, Trixie rescues them in her helicopter. On an icy road, Speed tries to pull ahead of the Car Acrobatic Team. The team thwarts Speed's attempt by knocking down icicles. Rounding an icy curve, the Mach 5's brakes fail. The car spins out of control and slides down the mountainside. Speed radios Trixie for help. The next morning, Speed catches up to Snake Oiler, whose car, along with others, is stopped at the most treacherous part of the course. Because of heavy rains, any car attempting to jump over the cavern would be sure to cause a landslide. The drivers decide to draw lots. Speed jumps and joins the wreckage below.

Speed enters the Mach Five in a demolition derby to convince a once-famous racer to be a real racer again.

Speed and his family are on the way to the Grand Prix (which is the key race for the World Racing Championship) and their plane is forced down on to an island by a storm. On the island they find out: that the both the plane's and Mach Five's radios have been smashed; every other passenger is in a hurry to get where they are going; there are no plants on the island, and that the island is a likely a forgotten top secret base used during a war. Since the island is uncharted Speed has no idea where to send the homing robot nor if the oxygen would last long enough to get help. Speed learns that one of the other passengers has brought advertizing balloons. Using hydrogen from the base Speed turns the Mach Five into a dirigible, then they draw lots to see which three people will go to get help. After the drawing, Trixie gives her lot to a girl whose mother is dieing, and the rich man buys a lot from one of the other winners. Spritle and Chim Chim stow away and force Speed to throw everything

At the racetrack, the Stunt Car Spectacular promises "action and thrills." Two contestants attempt to scale a ramp and clear a stack of cars, but fail.

Later, Speed and Pops head toward a difficult section of the course where each driver must leap over a deep cavern without plunging into the river 1,000 feet below. At the site, the Car Acrobatic Teams demonstrates their remarkable ability, twirling in the air over the cavern. Before Speed's attempt, Racer X offers advice. At Pops' garage, Pops wishes he knew the secret behind the abilities of the Car Acrobatic automobiles. Spritle and Chim Chim overhear this and sneak away at night to spy on the team. Spritle returns with photographs detailing the special devices that make the cars fly. Before long, the Mach 5 is outfitted with wings. Pops passes out from exhaustion.

This time, the old man accepts Speed's help. While the Racers dine with the old man, the granddaughter, and his adopted children, Blaggard steals the Model T, hoping that it is the one that once belonged to the crook Light Fingers Clepto. Speed vows to recover the stolen vehicle. The old man, unashamed, tells who his father was. Trixie spots the Model T from her helicopter and brings it into Pops' garage for repairs.

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 Sibana.

Speed and Mr. Force get into a fight and Mr. Force reveals that he cannot use his right arm and wears a metal brace on it. Mr. Force tells how he accepted money to throw a race but won it anyhow. The gangsters then crippled his right arm to prevent him from racing and have now wrecked his car. While Pops fixes the car Speed challenges him to drive the Mach Five with its manual transmition to help 'wake up' his right arm. The next day Mr. Force wins the Snake Track race but the gangsters come forward and reveal that he cannot use his right arm. Mr. Force proceeds to punch out the gangsters and Speed gr

Early morning, somewhere in Japan, a group of black three-wheeled cars approach a pagoda, which is called the Cupola Castle.
