In the near future, a new energy source called Lunarium (found on the Moon) helps countries around the world build cities and research centers on Mars, turning it into humanity second home.

Malaysia is selected by the United Nations to lead the Mars International Alliance (MIA), with Dato’ Fadillah appointed as the first President of Mars. The United States is represented by Ethan, who serves as the Second Vice President of MIA.

Soon, Chinese scientists discover a new mysterious crystal on Mars called Velocium. When combined with Lunarium, it creates Light-Speed Energy, allowing spaceships to travel at the speed of light. Secretly, Ethan forms a rebel group called Red Dawn, wanting Mars to break free from Earth’s control. He leads a coup, kills Dato’ Fadillah, seizes all communications, and blocks contact between Mars and Earth. Red Dawn also uses Velocium to build high-tech weapons, including light-speed fighter jets.

Because of Velocium’s intense radiation, all machines fail when they get close. Ethan enslaves the people of Mars, forcing them to mine day and night. Many die from radiation and exhaustion.

In this desperate moment, a Martian scientist named Hana hacks into Red Dawn’s system and sends a distress signal to Earth. The Grab Boy team quickly responds, leading the Lunar Defense Force (GDF) to Mars. Ah Boy still drives the older Taxi Myvi Mark 4.

As soon as they land, they are ambushed. The GDF suffers heavy losses, and the Grab Boy team is captured and sent to a prison camp. Seeing the pain of the people, Sam gives an inspiring speech in prison, awakening the spirit of resistance. The team begins planning an uprising. Scientists upgrade their battle suits with Velocium. Sam makes the battle plans, Meor trains the people to fight, Jay and Hana hack into Red Dawn’s systems, Ah Boy and the engineering team rebuild the Taxi Myvi, transforming it into the light- speed vehicle — Taxi Myvi Mark 5.

On the day of the counterattack, the People’s Army and the Grab Boy team launch a full-scale assault. However, Red Dawn’s overwhelming firepower crushes their efforts, and the uprising nearly collapses. Just then, Earth and lunar forces arrive on the battlefield. The Grab Boy team rallies the People’s Army for one final stand. In the end, Red Dawn is defeated, and Ethan escapes into deep space aboard a light-speed ship.

Mars is finally free. Hana is appointed by Malaysia as the new “President of Mars” to lead its rebuilding. Malaysia forms the Martian Security Force, working with Earth and the Moon to protect peace across the galaxy. In the central square, the people of Mars build a statue of the Grab Boy team standing on the Taxi Myvi, holding the Malaysian flag — a symbol of unity, courage, and hope for galactic peace.
