Frank and Joe are working on a high-risk, high-stakes undercover operation. A hijacking ring is spreading terror through New York, snatching high-priced cars at gunpoint. Posing as expert thieves, the boys follow the gang from the streets of the city to the islands of the Caribbean -- into the heart of an international black-marketing scheme!

But down in the islands, it's open season on the Hardy boys. Cut off from the outside world and from outside help, they discover that their cover has been blown. They're driving a dangerous road -- hard and fast and slick -- and one slip of the wheel could lead to a deadly end. But when Frank and Joe get in gear, there's no turning back.
