The first title from the exciting series made up from the BBC's natural history output. Just the sight of a shark's fin breaking the surface spells terror. Underwater filming of these awesome, two ton, 19 foot fish in their natural unbaited environments exposes the Great White as a paradox: a shy and cautious creature existing within a highly structured social order, but also a terrific killing machine striking with total surprise and devatating speed from the murky depths.
