While Charlie and Cappa are away from Z-Tech, William has been raising an empire of his own - one determined to crush any who interfere with his plans for world domination. Worse, he's sided with the only other organization who had almost succeeded in erasing Z-Tech from the global market, pitting Anne and her friends in a desperate struggle for survival. The enemy has the advantage of numbers, but Z-Tech has Zima - a one-person army in her own right. Only time will tell if she's enough to offset the overwhelming forces set against Z-Tech, and if San Francisco will survive their battle.
