In search of stolen jewels, the Hardys plunge into a sea of danger!
Surf's up and so is crime... And Frank and Joe are in for one wild Hawaiian ride!
The Hardy's Christmas in paradise, Hawaii-style could turn out to be one big wipeout. Checking out the world-famous dolphin research center at Nai'a Bay, the boys discover that one of the dolphins has suffered a suspicious injury ... and that one of the researchers has vanished without a trace. All evidence points to kidnapping!
Frank and Joe are convinced that the disappearance is linked to the notorious Hawaii Heist. A cache of hot jewels was lost at sea in a plane crash, and the race to recover them has turned into a deadly battle of wits, fists, and spear guns. The Hardys are headed for treacherous waters -- stirring up trouble and swimming with the sharks!
