デジモンセイバーズ3D デジタルワールド危機イッパツ！

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.

Upon arriving at the Digital World after the "reboot", the Digidestined are hunted by a new villain. Meanwhile, Sora is troubled by her partner Digimon's indifference towards her.

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.

Takuya Kanbara, Koji Minamoto, J.P. Shibayama, Zoe Orimoto, Tommy Himi, Bokomon, Neemon ride a Trailmon (Ball) through a desert when they get caught in a battle between human and beast Digimon. It is interrupted by the Lost Island, an island trapped between dimensions, crashing down between them and scooping all involved up.

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

Omnimon confronts Mephistomon (who was formed from Apocalymon's data) in a dark corner of the Digital World over Mephistomon's attempt to destroy both the Digital World and the Real World and incorporate the data in order to become truly invincible. They fight, but then Mephistomon sees a chance and slips into the Real World.

In this movie, that takes place three months after MaloMyotismon's defeat, the DigiDestined go up against Diaboromon again. Tai and Matt head back to the Internet to deal with him with Omnimon, while the younger Chosen Children go to deal with the rampage of a swarm of Kuramon (Diaboromon's Fresh form). With the help of Angemon and Angewomon (with T.K. and Kari), Omnimon was able to destroy Diaboromon again, but it turned out to be a trap, as his destruction allowed many more Kuramon to go to the Real World. Things go out of control when the Kuramon in the Real World merge to create a Mega level called Armageddemon, an alternate Mega in Diaboromon's evolutionary line. It is so powerful that neither Omnimon nor Imperialdramon were able to defeat it on their own.

Months after the events of the first season, a Digimon called Diaboromon appears and starts attacking the Internet. The children and their Digimon unite once more in order to prevent him from destroying every communications network on the planet.

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.

The world has begun to collapse. The rampaging Meicoomon absorbs Tailmon, who underwent a dark evolution, and changes form into the immensely powerful Ordinemon. In accordance with Yggdrasil's expectation, the real world is about to be engulfed by the Digital World. Meanwhile, Homeostasis considers Ordinemon to be out of control and puts into motion its final plan that will entangle the real world. Then the time comes for the DigiDestined to arrive at a final decision. What future do they choose for themselves?

Two children receive a strange egg that hatches into their very first Digimon, leading to the night that would change their lives forever.
