In a sleepy lagoon off the coast of Japan is a highly guarded secret. During the night, Taiji fishermen engage in an unseen hunt for thousands of dolphins.

When a team of elite activists, filmmakers, and free-divers embark on a secret mission to penetrate the cover, the shocking discoveries they find there are just the tip of the iceberg. Includes commentary, deleted scenes, and more.
