Gennai appears and says there is an eighth DigiDestined and that Myotismon is planning to go to the Real World with an army of evil Digimon to find him/her. This is the English dubbed version of the series.
While at camp, Tai, Matt, Sora, Izzy, Mimi, Joe, and T.K. come across seven Digivices and are transported to a strange Digital World where they make friends with creatures called Digimon who claim to be their chosen partners.
The kids come across a beach with numerous phone booths, but none of them seem to work. As they sit down for a break to eat, a wild Shellmon appears and attacks the kids.
The kids run away from a Monochromon battle. They come across a trolley car on a small island and decide to spend the night in it, until they are attacked by a Seadramon.
The kids come to a Yokomon village to rest for the evening. A Meramon attacks the village and Biyomon digivolves to Birdramon to defeat him, causing a Black Gear to be expelled from his body.
The kids stumble upon a factory where they find an Andromon in trouble. After they help him he attacks them. Izzy discovers coding, which he uses to digivolve Tentomon into Kabuterimon.
While escaping the Numemon who attacked the group in the sewers on their way out of the factory, the kids are split up and Mimi ends up in Toy Town after being attacked by a Monzaemon.
Tai and Matt argue whether they should climb Infinity Mountain. Joe and Gomamon decide to climb the mountain by themselves. While on the mountain, they are attacked by a Unimon.
The kids meet the ruler of File Island, Devimon, the controller of the Black Gears. He, Ogremon and a possessed Leomon, attack the kids who manage to escape, but Devimon breaks File Island into multiple, smaller islands.
Tai and Agumon land on a snow-covered island and are forced to defeat a Frigimon. After destroying the Black Gear they cross over to the island where Matt and Gabumon landed.
Mimi and Palmon escape Sukamon and Chuumon and cross over to the next island where Izzy and Tentomon landed, but end up getting lost in a labyrinth and attacked by Centarumon.
