A theme park attracting 65,000 visitors daily, Utopia is a world on the cutting edge of technology, complete with robots and futuristic holograms. But when ominous mishaps begin to disrupt the once-flawless technology, Dr. Andrew Warne, the brilliant computer engineer who designed much of the park's robotics, is summoned to set things right. On the day he arrives, Utopia is rocked by something far more sinister. A group of criminals has infiltrated Utopia's computerized infrastructure and gotten control of all its attractions and systems. Their threat: that if their demands aren't met, every man, woman, and child will become a target. Now Warne must try to save the lives of thousands of innocent people, and among those unsuspecting crowds is his only daughter.
