Three years after the events of Digimon Adventure 02, Taichi Yagami is now in high school, downhearted that none of his friends are able to come to his soccer game and feels that they are slowly drifting apart. Meanwhile, strange occurrences are causing electronic devices to malfunction across Odaiba. Minutes before Taichi’s match begins, a Kuwagamon that had been causing the malfunctions suddenly appears, soon taking physical form and causing collateral damage to the city. Just as Taichi is cornered, his Digivice shines and his old partner Agumon appears while digivolving into Greymon to fight the stronger Kuwagamon. As the two Digimon end up traveling through portals to an airport in Haneda, Taichi is given a ride by his substitute teacher, Daigo Nishijima. As more Kuwagamon appear, Taichi is joined by the other DigiDestined and their Digimon partners, with the exception of Joe, who defeat two of them, while a mysterious hand appears and destroys the last one.
