The New York State presidential primary is in full swing, and Nathan Webster, computer scientist turned independent candidate, is offering some exciting new ideas for the future. Frank and Joe are eager to hear his major campaign speech in Bayport. But Webster is also attracting a more sinister kind of attention...a kind that could prove fatal!

When a bomb disrupts Webster's Bayport appearance, the Hardys sign on as bodyguards -- determined to insure that the candidate can run for office without running into danger. But in protecting Webster, they too become targets of terror. And if Frank and Joe don't catch up with the stalker soon, they could all end up out of the race for good!
