While at summer camp, seven kids come across seven Digivices and are transported to a strange digital world. In this new world they make friends with creatures that call themselves Digimon who were born to defend their world from various evil forces.

It's the year 2020. The Network has become something humans can no longer do without in their daily lives. But what humans don't know is that on the other side of the Network is the Digital World, a realm of light and darkness. Nor are they aware of the Digimon who live there. Fifth grader Taichi Yagami's mother and little sister Hikari went to Shibuya, and now they're aboard a runaway train. Taichi hurries to Shibuya to save his mother and sister, but the instant he heads toward the station platform... a strange phenomenon befalls the DigiDestined, and Taichi goes to the Digital World!

Tai is now a university student, living alone, working hard at school, and working every day, but with his future still undecided. Meanwhile, Matt and others continue to work on Digimon incidents and activities that help people with their partner Digimon. When an unprecedented phenomenon occurs, the DigiDestined discover that when they grow up, their relationship with their partner Digimon will come closer to an end.

A crowdfunding campaign opened for the "Digimon Adventure Memorial Story Project." It was for 5 shorts that included a prequel of the upcoming film and side stories about the daily lives of the Digimon characters and their partners, which are stories that did not make it into the film.

Spring break turns into a summer war when the evil Diaboromon wreaks havoc on the internet, and Tai and Matt must achieve a new Digivolution to defeat him! Will Tai and the Digidestined save the world, and will Sora ever forgive Tai for giving her a hair clip?

After years of inactivity, the DigiDestined regroup with their Digimon to save their world, but have the years changed their characters too much?

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 DigiDestined go to a nearby hot springs theme park and everyone has a good time, but Joe doesn't show up because he wants to study for his exams. Another infected Digimon, Ogremon, attacks Odaiba. Gomamon runs away from home while Mimi faces problems with the other DigiDestined and her classmates because of her selfish ideas.

Digimon Adventure 3D: Digimon Grand Prix! was first shown in July 2000 in Sanrio Puroland and in Sanrio's character theme park Haromy Land. The movie was later rerun at Toei's anime festival "Tobidasu! 3D Toei Anime Matsuri" on 03.10.2009. Together with Digimon Savers 3D: Digital World Kiki Ippatsu!, and 2 other CG anime works by Toei, it was released on DVD on 21.02.2010.

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.

The eight original Digidestined go on a camping trip together on August 1, even if the others were a bit busy. The planned camping trip pushes through, but Mimi suddenly forgets the camping equipment, and things go wrong pretty fast. But then, Taichi remembers that this is exactly like their first camping trip together… to the Digital World. But as they go about their camping trip, the camping grounds slowly reveal its hidden secrets.
