1. Ocean of Fear: The Worst Shark Attack Ever

This two-hour special kicks off SHARK WEEK's 20th Anniversary and is narrated by Richard Dreyfuss, who memorably played Matt Hooper in Jaws. The special tells the gripping story of the crew of the U.S.S. Indianapolis, sunk by two torpedoes in the Philippine Sea on the night of July 30, 1945. Eight hundred sailors, many maimed and burned, were plunged into the water … and floated helplessly for four days, having to deal with hunger, driven mad by thirst, and menaced by hundreds of sharks.
