To separate fact from fear, NOVA teams with leading shark experts in Australia and the United States to uncover the science behind the great white's hunting instincts. With shark populations plummeting, scientists race to unlock the secrets of these powerful creatures of the deep in their quest to save people -- and sharks.

A journey into the land of sharks.

"Kon-Tiki" was the name of a wooden raft used by six Scandinavian scientists, led by Thor Heyerdahl, to make a 101-day journey from South America to the Polynesian Islands. The purpose of the expedition was to prove Heyerdal's theory that the Polynesian Islands were populated from the east- specifically Peru- rather than from the west (Asia) as had been the theory for hundreds of years. Heyerdahl made a study of the winds and tides in the Pacific, and by simulating conditions as closely as possible to those he theorized the Peruvians encountered, set out on the voyage.
