The Cove begins in Taiji, Japan, where former dolphin trainer Ric O'arry has come to set things right after a long search for redemption. In the 1960s, it was O'Barry who captured and trained the 5 dolphins who played the title character in the international television sensation "flipper."

But his close relationship with those dolphins - the very dolphins who sparked a global fascination with trained sea mammals that continues to this day -- led O'Barry to a radical change of heart. One fateful day, a heartbroken Barry came to realize that these deeply sensitive, highly intelligent and self-aware creatures so beautifully adapted to life in the open ocean must never be subjected to human captivity again. This mission has brought him to Taiji, a town that appears to be devoted to the wonders and mysteries of the sleek, playful dolphins and whales that swim off their coast.

But in a remote, glistening cove, surrounded by barbed wire and "Keep Out" signs, lies a dark reality. It is here, under cover of night, that the fishermen of Taiji, driven by a multi-billion dollar dolphin entertainment industry and an underhanded market for mercury-tainted dolphin meat, engage in an unseen hunt. The nature of what they do is so chilling -- and the consequences are so dangerous to human health -- they will go to great lengths to halt anyone from seeing it.
