Human intervention in the natural balance, especially such a cruel manifestation as smuggling, annually causes irreparable massive damage to our planet. Actions of criminals are prosecuted by law, animal protection societies are created, and the oceans are organized, and raids are conducted against the favorite places of smugglers. The documentary criminal film The Cove (2009) opens a shocking truth to the audience about one of such places located in Japan, in Wakayama Prefecture. Local millionaire fishermen drive mammals into a trap, from which animals have no way out. Every year more than twenty thousand of these noble animals die like this. Authorities of Japan are aware of what is happening, but they refuse to apply the measures. The cruel business of Japanese anglers is told by the crew and the ex-dolphin trainer Roy O'Berry.
