The film is an edited version of three different Japanese short films, which have been combined together. There is narration by a continuing character, Kari. The first segment of the film revolves around the first encounter with a digimon and a fight that occurs between their digimon and another. The two kids, Kari and Tai, raise a fast-growing digimon from an egg to a large, dinosaur-like digimon, which escapes from their house and then has an encounter and a battle with a parrot-like digimon. The second segment mainly involves Tai and another digiDestined friend of his, Izzy. A computer virus sweeps across the internet, effecting a digiEgg, and thus creating an infected digimon. This infected digimon begins to start eating computer information and data, and the two protagonists attempt to stop the digimon, but fail.
