Frank and Joe's new classmate Lindsey Nichols is more than drop-dead gorgeous -- she's pure trouble. An expert motorcyclist, she loves to take risks, and wherever she goes, danger is sure to follow. Her father's company is putting a classic bike back on the market, and the plan has led to a high-stakes corporate dispute.

When the Hardys take sides, they also find they've taken their lives in their hands. Someone's out to kill the new bike before it hits the market -- and killing may be the only way to do it. Dodging firebombs, bullets, and muscle-bound, chain-wielding bikers, Frank and Joe vow to down the saboteur before the fight spins out of control!
