Oscar winner Halle Berry stars as a shark expert who accepts a lucrative business offer, only to become stranded in "Shark Alley" and hunted by nature's most dangerous predator in this deep-sea thriller from director John Stockwell (Blue Crush, Into the Blue). Kate (Berry) earned the nickname the "Shark Whisperer" for her remarkable ability to bond with some of the most feared creatures on the planet. But when Kate witnesses one of her fellow divers getting killed during a brutal shark attack, the resulting trauma renders her incapable of braving the ocean depths. Meanwhile, the bank threatens to foreclose on Kate's boat and it begins to look as if her career has become stranded ashore. Kate soon gets the opportunity to settle her debts, however, when her ex Jeff (Olivier Martinez) introduces her to a wealthy entrepreneur who's willing to pay a lot of money to experience the thrill of swimming with sharks, sans cage. Reluctantly, Kate agrees to lead the dive. But shortly after steering their boat into Shark Alley, all of her greatest fears begin to come true.
