Taichi Yagami and his friends have moved on to junior high, but by that time, they have lost contact with their Digimon partners. Taichi is therefore surprised to suddenly receive a distress call summoning him to the Digital World. Once there, he learns that Digimon are living in fear of the mysterious Digimon Emperor, who is somehow suppressing their ability to Digivolve! In the real world, Hikari Yagami and Takeru Takaishi reunite in the same fifth grade class. They share three schoolmates: Daisuke Motomiya, who reminds them both of Taichi; Miyako Inoue, a technical wizard; and Iori Hida, Miyako's neighbor. When these three children receive D-3 Digivices, they—along with Hikari and Takeru, who still possess their own original Digivices—comprise the new generation of Chosen Children who must save the world once again. With the power of the Armored Digi-Eggs, they must thwart the Digimon Emperor's plans to spread his influence over the entire Digital World.

The gate to the Digital World has been closed for three years. Taichi Yagami and his friends have since moved on, and now that he is in his second year of high school, it is time for him to grow up. While everyone else knows what they want to do with their lives, Taichi remains unsure. Meanwhile, the group drifts further apart as they follow their own paths. One day, a rogue insectoid Digimon called Kuwagamon materializes and disrupts electronics all over the city. Taichi recklessly chases after it and ends up cornered by the attacking Digimon. Suddenly, the Digivice that he still carries—a digital device that serves various purposes including helping one's Digimon partner to evolve—glows, and Agumon appears. The two are able to defeat Kuwagamon, but why did the Digimon cross over to this world in the first place? What is happening in the Digital World, and how exactly does this involve Meiko Mochizuki, the new transfer student in Taichi's class?
