Time has passed since that summer adventure, and there are even more children with partner Digimon now. However, because of their unique nature, many children face the looming shadows of persecution and being targeted for military use. While Taichi and Yamato are working to rescue children, they are attacked by mysterious Digimon.

Meicoomon rampages after witnessing Meiko Mochizuki being injured by the man bearing Gennai's likeness. "It would have been better if you hadn't been born..." Meicoomon disappears into the Real World, which has since become distorted. Possessing overwhelming power, she's the key to the world's destruction.

After seeing Meicoomon's abrupt transformation and killing of Leomon, Agumon and the other Digimon are kept isolated in Koushiro's office in order to prevent them from infection, but signs of infection begin to appear in Patamon.

The film begins with around Agumon, Gaomon and Lalamon, whose partners have been placed in a magical slumber along with the rest of city's population, by a mysterious thorned vine that spread throughout the city. As the Digimon make their way through the silent city, they stumble upon a pack of Goblimon, led by an Ogremon, who are attacking a young girl. They scare off the goblins, and the girl, Rhythm, reveals that she is actually a Digimon, then explains that the thorns are the work of a Digimon named Argomon. The quartet sets out to confront the villain atop his skyscraper lair.

The Digital World is becoming so overpopulated that the super computer Yggdrasill who governs the Digital World can no longer handle it. Its solution is Project Ark: to wipe out most of inhabitants with the X Program. Yggdrasill chooses a very small percentage to be moved to a new Digital World and then proceeds to destroy the old one. Some Digimon who were not chosen survive anyway, and they move to the new world with a rare gift known as the X Antibody; this antibody changes their appearance and makes them more powerful, while at the same time making them immune to the X Program. No longer in control, Yggdrasill uses the Royal Knights to destroy these X-Digimon, who are outcasts in the new Digital World.

Six months after the D-Reaper was destroyed, the Tamers are planning to throw Rika a surprise party, but Rika finds out. Suddenly a train-Digimon named Locomon begins to race around the tracks, causing havoc. The Tamers respond to this, as Takato digivolves Guilmon into Growlmon to stop the train Digimon but fails as Takato, Rika and Renamon get on it in an attempt to slow it down. The others, excluding Suzie, use a freight train to catch up with Locomon

When a powerful new Internet Digimon hatches and begins to consume data at an alarming rate, the Digidestined - kids chosen to save the digital world - must put an end to the destruction before the damage becomes irreversible and worldwide communication halts forever. As computer-based missiles are launched, and a wayward Digimon kidnaps the Digidestined, only the combined efforts of a worldwide network of kids and a new group of "Digidestined" can rescue the others and stop global disaster.
