For years, Taiji, Japan concealed a dark secret — an annual six-month long dolphin hunt, where thousands of dolphins are brutally slaughtered in a tiny, hidden inlet known as "The Cove." In 2009, the Oscar winning film, THE COVE exposed Taiji's hunt to the world for the first time. Dolphin activist Ric O'Barry starred in the film, which also detailed his 40-year quest to save dolphins in trouble. Ric is accompanied by his son, filmmaker and fellow activist Lincoln, and a camera crew on the return to the killing cove for the first time since the film's release. Unlike previous visits, where Ric often operated undercover, this is a very public mission. He and Lincoln are surrounded by a troupe of Japanese journalists interested in learning more about the O'Barrys activities and dolphins. The mission now is to stop the hunt by wielding the power of international outrage and opinion. At first, the mission appears to work — the hunt is delayed and a covert swim to the Cove itself shows no apparent preparations to resume the slaughter. But once Ric and Lincoln leave Taiji, a single phone call brings them rushing back. The hunt has resumed. There are dolphins in the killing cove.
