Upon arriving back into their own time, Austin and the others realize that the present day they have returned to is not the same one they left before. Unfortunately, our heroes find out that they are not the only ones who know how to alter time. Pete has returned to seek revenge, and he has altered time in order to get the upper hand. Luckily, our heroes find out about a group called the Dominating Dozen: a group that they had been a part of in this new dimension, and that the only way of defeated Pete is by bringing the other members of this once infamous group back together.
