The film highlights the fact that the number of dolphins killed in the Taiji dolphin hunting drive is several times greater than the number of whales killed in the Antarctic, and reports that 23,000 dolphins and porpoises are killed in Japan every year in the country's whaling industry. The migrating dolphins are herded into a hidden cove where they are netted and killed by means of spears and knives over the side of small fishing boats.
According to the Ministry of Agriculture, Forestry and Fisheries of Japan's most recent progress report 1,569 cetaceans in Taiji were killed during the 2007 season, including methods other than drive hunting. The Ministry claims that only 1,239 cetaceans were killed by drive hunting, and that a total of 13,080 cetaceans were killed throughout Japan in 2007.
The film was directed by former National Geographic photographer Louie Psihoyos. Portions were filmed secretly during 2007 using underwater microphones and high-definition cameras disguised as rocks

PLOT-Plot
In the 1960s, Richard O'Barry enjoyed a lucrative career as a specialized animal trainer; he captured the five dolphins that were used in the popular television series Flipper, and taught them the tricks and special commands they used on the show. Four decades later, O'Barry has renounced his former life as a trainer and become an animal rights activist, speaking out against the hunting of aquatic mammals and keeping them in captivity. O'Barry is not welcome in Taiji, a town along the Japanese coast where hunting dolphins is a major part of the local economy, but he and a group of activist filmmakers made their way into the city as well as the carefully guarded harbor in hopes of documenting the abuse of dolphins by fisherman and the poisoning of the waters that has taken a toll on the marine ecology. O'Barry and his colleagues captured some beautiful underwater footage as well as shocking images of how the town's fisherman have sullied the dolphins and their habitat, and director Louie Psihoyos has used this material as the basis for the documentary The Cove, which received its world premiere at the 2009 Sundance Film Festival. - Mark Deming, Rovi
