Drew now knows the real mission her creators were trying to accomplish; create a perfect world. In other words, taking people, eventually all of the people on earth, and turning them into mechanically altered, perfect, human beings. That is what Drew previously found out happened to her.
But, although Drew, Jessica and Michael know that they need to somehow stop the creators, Drew also knows that she's made another enemy along the way; one possibly even more dangerous than the creators.
As Drew struggles to detach herself from the people who "created" her and untangle the mess they've made, she discovers that it might not be as easy as she thought, that she is destined to play a larger role in this plan than she ever intended.
