The film series is set three years after Digimon Adventure 02. A mysterious anomaly is causing distortions in the Real World and Digimon are being plagued by a virus that turns them hostile. These circumstances lead to the DigiDestined being reunited with their partner Digimon. Joined by another DigiDestined named Meiko Mochizuki and her partner Meicoomon, they must not only deal with the mystery of the infected Digimon but also with the responsibility of growing up.
Tai, now in high school, feels downhearted that his friends are slowly drifting apart. Meanwhile, strange occurrences are causing electronic devices to malfunction across Odaiba. Minutes before Tai is set to play a soccer match, Kuwagamon appears and invades the city, causing electronic malfunctions. Just as Tai is cornered, his Digivice shines and Agumon appears. He digivolves into Greymon and fights with Kuwagamon, ending up at Haneda Airport. Tai gives chase by hitching a ride with his homeroom teacher, Daigo Nishijima. As more Kuwagamon appear, Tai is joined by the other DigiDestined and their partner Digimon, who defeat two Kuwagamon before Alphamon intervenes and crushes the last one.
