In San Francisco to attend VidCon, a video game convention, the Hardys uncover a case of high-tech industrial espionage. The Xyrodian Corporation has lost some of its most futuristic designs to the black market. And as Frank and Joe seek to trace the piracy to its source, they discover that the video games have taken on a new -- and dangerous -- dimension!

But they know that the ultimate challenge will come at the hands of a computer and criminal mastermind -- an elusive foe who has already demonstrated a real genius for murder!
