A re-interpretation of Ramayana, the Thai animation film tells the story of a giant robot, Na Kiew, who's left wandering in a barren wasteland after a great war. Na Kiew meets Jao Phuek, a puny tin robot who's lost his memory and is now stuck with his new big friend. Together they set out across the desert populated by metal scavengers, to look for Ram, the creator of all robots.
Decades prior to the start of the film, the American military sponsored a superhero group called "Team Zenith." Its leaders were Jack Shepard, a.k.a. "Captain Zoom", who possessed super-speed, and his brother, Connor, a.k.a. "Concussion", who could project sonic blasts. The military tried to increase the team's powers by exposing them to an experimental form of radiation called "Gamma-13". This caused Concussion to become more powerful, but it also reversed his personality. Thinking Zoom and the team betrayed him, Concussion went insane and killed his teammates Marksman, Ace, and Daravia. Concussion was believed to be killed by Zoom in an explosion, but he had been sent into another dimension instead. Zoom lost his powers, and his brother.
In Gaea’s atmosphere the Jointrons and the Seacons battle each other but both factions are interrupted by the arrival of a large space ship which rams into them and sends them all flying into space before crash landing on the planet, and the Maximals and Predacons are immediately alerted. On the Galvaburg II, Gigastorm recommends destroying the ship but Galvatron is interested and believes it may hold good fortune for the Predacons. On the Yukikaze Lio Convoy orders a unit sent to investigate the ship but Lio Junior, Lio Convoy’s son, wishes to go but the other Maximals shoot him down, but Tasmania Kid stands up for him and asks if both can go and Lio Convoy approves and has Stanton and Skywarp accompany also. The 4 Maximals arrive at the ship and discover a “teleport gate”, an ancient device capable of opening a doorway into the past and transporting any living creature into the present, Transformers included but it requires a control unit to function. When Lio Junior finds it the Predacon Combaticons Hellscream, Dirgegun, Thrustor and Max-B swoop in and steals it but Lio Junior dives off after it alone and the Predacons overpower and nearly kill him, but before Hellscream can fire a finishing blow Kid takes the hit as the other Maximals arrive and scare off the Predacons and secure the control unit.
