Highway Robbery

"When you pack a valuable load, you always ride with danger.

The highway can be a very dangerous place -- especially when you're carrying a heavy cargo. The Hardys have gone undercover, determined to crack a truck hijacking scheme, but a ruthless gang of thugs are just as determined to run them off the road.

The hijackers are spreading terror on the interstates, and whoever gets in their way could end up on a one-way dead-end street. Someone's going to eat asphalt, but Frank and Joe are prepared. They're gunning the engines and riding the roads on eighteen wheels of diesel-powered chrome and steel."
