Four years have passed since the original eight Digidestined kids defeated the evil forces that threatened the Digital World. Now T.K. and Kari must lead three new Digidestined on a quest to conquer another dark force that puts both the Digital World and the real world in great danger. The kids lead secret double-lives, as they leave the real world and enter the Digital World each day after school. When the five young heroes first arrive in the Digital World, Kari and T.K. reunite with Gatomon and Patamon and the new kids meet their own new Digimon friends. Together with their Digimon, the kids must unveil the mystery behind the new villain and stop him before it's too late!

Due to the dark rings, control spires and the fact the monsters are all a lot stronger the older 6 original digidestined's and their Digimon can do little to nothing to help.

As long as the control spires are standing the original digidestined's Digimon can't digivolve! But with out that tower they are free to digivolve!
