Matthew McConaughey stars as explorer and adventurer Dirk Pitt in this adaptation of the best-selling novel by Clive Cussler. Pitt thinks he may have found both a fortune and the answer to a long-standing mystery when he discovers a rare coin in the waters of a river in West Africa. During the Civil War, an ironclad battleship with a valuable cargo went missing, and Pitt’s theory is that the coin places the ship somewhere in the Sahara Desert. Pitt and his goofy sidekick, Al Giordino (Steve Zahn), set out to find it, but along the way they make the acquaintance of Dr. Eva Rojas (Penélope Cruz), a scientist and physician who is trying to determine the source of a strange and deadly disease sweeping the nation. As Eva joins Dirk and Al, they begin to wonder if the mysteries they're trying to uncover might be somehow linked. Sahara was only the second of Cussler's Dirk Pitt adventures to be adapted for the screen; the first, 1980's Raise the Titanic, was publicly dismissed by the author. ~ Mark Deming, Rovi
