Izzy falls victim to Vademon, a Digimon who preys on curiousity, and becomes lost, both physically and mentally, in another dimension.

Synopsis
Izzy and Tentomon, on a rocky path, find themselves surrounded by signs warning them to turn back. The ground crumbles form underneath them, sending them into darkness. As he falls, Izzy hears a voice which accuses him of being greedy when it comes to knowledge, and demands that he give up his curiousity. (In the original Japanese, the voice demanded Koushiro's "inner heart".) With no other options, Izzy gives in. Moments later, he and Tentomon are floating through endless space, and the mystery voice reveals itself as the Big-brained Digimon, Vademon, telling Izzy to forget everything. Tentomon's attempts to bring back the old Izzy fail as Izzy pushes him away. Meanwhile, DemiDevimon offers a piece of his curiousity to Vademon in exchange for Izzy's crest. Back in endless space, Tentomon has de-digivolved to his weakest form, Pabumon, and catches Izzy's attention. Pabumon reminds Izzy of the times they've had together, and Izzy snaps out of his dozy behaviour. They then find their way into Vademon's store room where Izzy's curiousity is held, but not before Vademon discovers them and chases them back into his 'endless space' dimension, where a battle begins and Pabumon digivolves up to the ultimate MegaKabuterimon. He destroys Vademon's dimension, and carries Izzy out of an enormous explosion back outside, where Matt and T.K. are waiting for them.
