It's the year 2041. Six women represent America's best hope for survival. Organized into three 2-person crews, they man three prototype assault tanks built for the U.S. Military. These prototypes, in field test, survived a cascade of political events that led to complete destruction of the Earth. These six women represent the last vestige of order and civilization in a world that no longer has either. However, they are not the only surviving power. Nor are they the only ones fighting for control. Instead they have become the last defenders of all who survive in a world where there is no one else left to turn. Yes, they are the Last Defenders. Never has so much depended on so few.
