Renny Harlin places his cast of shark chum on a techno-cool atoll where Saffron Burrows has enlarged the cerebellums of three sharks in search of an Alzheimer's cure. After one of the lab sharks gets loose, the man with the money, Samuel Jackson, drops in on the clam shack to see how his dollars are working. A storm cripples the structure and everyone sits around waiting to become shark hors d'oeuvres. Harlin does keep the suspense strung tight, but the über-sharks' omnipotence borders on cheesy, unintentional camp.
