While at summer camp, seven kids come across seven Digivices and are transported to a strange digital world. In this new world they make friends with creatures that call themselves Digimon who were born to defend their world from various evil forces.

With most of the original characters now in junior high school, the Digital World was supposedly secure and peaceful. However, a new evil has appeared in the form of the Digimon Emperor, a human just like the DigiDestined, who has been enslaving all Digimon. Three new children are chosen to save the Digital World and, along with T.K. and Kari, make up the new generation of DigiDestined.
