In order to defeat the mysterious Black Armor troops, General Yuan, the commander-in-chief, specially selects five elites – LM, SK, SR, TL and BT – to form World Peacekeepers, abbreviated as WPK. They are then given permission to use Ammobots, newly developed mechanical armors. WPK is entrusted with the huge responsibilities of defeating the Black Armors and protecting Marty, a boy with prophetic abilities. One day, Marty has a vision of a collapsing bridge, and it seems a flood is about to break out.
Marty's vision makes LM very anxious, and LM forces Marty to offer more predictions, much to the chagrin of everyone who thinks that he is being unreasonable. General Yuan reveals that LM's father, who was his comrade 20 years ago, died in a flood relief rescue mission. Everyone thus learns to empathize with LM. In the meantime, the weather begins to deteriorate. The WPK members request in unison to conduct another search operation and General Yuan allows them to do so.
The WPK sets off on a mission of searching for the collapsing bridge. It turns out to be a tall order and after a wild-goose chase, even Marty begins to doubt his own prophetic abilities. General Yuan then decides to call off the search operation. Incidentally, just as Marty begins to feel dismayed, he sees the actual car that got washed away by the flood in his vision. Thus, after a difficult journey, WPK finally finds the collapsing bridge they have been looking for.
After investigating the area near the collapsing bridge, the WPK realizes that many of the trees at the upstream of the river have strangely disappeared. At this moment, the Meteorological Administration announces a cloudburst warning. A flood seems imminent. As the WPK members descend the hill, they are ambushed by a unit of Black Armor troops and several other Black Armors surround Marty. The WPK members are torn between the need to rescue Marty and the need to contend with the flood.
As the WPK puts up a tough fight and manages to defeat the unit of Black Armor troops, Marty's vision turns into reality and the car is washed into the river. LM jumps boldly into the river and successfully rescues the driver who has been hurled into the water, thus making up for the regret he felt when he saw his father being swept away by the flood back then. As the WPK is trying to decipher the actual intention of the Black Armors, the Black Armor troops reemerge to wreak havoc at another location on Earth.
Numerous drifting icebergs start emerging erratically at the seas near the Arctic. Coupled with strange winds, they pose a threat to the ships navigating the area. International environment protection organizations thus seek help from the WPK. Refusing to heed his good friend General Yuan's advice, Professor Chin slogs his guts out to improve the performance of the Ammobots at the expense of his health and eventually falls ill. General Yuan then prohibits Professor Chin from entering the laboratory and the both of them begin a cold war with each other.
The WPK members encounter strange, strong winds as they are carrying out their mission at the Arctic. SK notices a mysterious dark shadow and makes a rash decision to disobey the rules and pursue the huge shadow alone, but to no avail as the shadow disappears subsequently. LM then reprimands SK and their relationship becomes strained. SK secretly leaves the hostel to pursue the shadow again and is discovered by LM, who tries to stop him. However, at this time, the ice cracks, leaving the two of them stranded on a piece of floating ice.
LM and SK wait for help from the other team members as they are left stranded on the piece of floating ice. While the both of them are left isolated, a polar bear attacks them, but LM's quick-wittedness saves the day. After this incident, SK starts to change his opinion of LM. As the other WPK members arrive, the mysterious dark shadow reappears and all of them jointly pursue the shadow.
After chasing the huge shadow for some time, the WPK notices that it disappears after plunging into the ocean. They then use Professor Chin's new invention, the Water Propeller, to conduct an underwater investigation and discover that the dark shadow is linked to the Black Armors. At this moment, Marty has another prophetic vision.
The WPK resorts to ways and means to lure the Black Armors out of the ocean, and the two camps have an intense showdown on the ice, with the WPK eventually emerging victorious. After this battle, SK becomes less hostile to LM, while General Yuan and Professor Chin bury the hatchet. The head of the Black Armors, Commander Nick, emerges to pronounce the WPK as their top enemy and vows vengeance.
Commander Nick storms the battlefield in a mysterious Black Armor, attempting to blow up the fuel depot to create a massive explosion in order to defeat the WPK. Marty learns about Commander Nick's intention through his prophetic abilities, and the WPK manages to stop the explosion in time, thus saving everyone from danger and foiling Commander Nick's plan. When Commander Nick learns about Marty's prophetic abilities, he vows to destroy Marty in order to nip the problem in the bud.
