Xoc explores the ocean's wonders through the eyes of a great
white as it treks from the Farallon Islands off the coast of California to the
warm waters of Hawaii some 2,300 miles away. Along its journey, the 17-foot
shark encounters natural prey and predators - from skittish seals to
brazen orcas - as well as man-made impediments that threaten not only the
giant fish, but the balance of ocean's ecology.
