This stunning and dangerous limited series spotlights both the controversial Japanese whaling trade and the tactics that the Sea Shepherd Conservation Society and its staff and volunteers use to cripple it. Aboard the Motor Yacht "Steve Irwin" the group seeks out the Japanese whaling fleet and then uses it's Delta Zodiac, helicopter, and other innovative techniques to enforce the law, including close-quarters ship-to-ship contact, to disable and/or sink the Japanese whaling ships in the fight to enforce international laws on the high seas where law enforcement is minimal or non-existent. The successful confrontations disrupt whale carcass processing and disperse the fleet of whaling vessels.

Whale Wars is back for a new adrenaline-fueled season, and after last year's victorious campaign the Seas Shepherds thought they had ended whaling in the Southern Ocean once and for all. Surprisingly, the Japanese are returning stronger than ever with a military convoy and zero tolerance. Anticipating the battle of a lifetime, the crew is once again are trolling the Antarctic with surprise tactics, intense strategy and unparalleled passion.
