The Sea Shepherds depart on a campaign with a new vessel in their fleet, The Gojira. Early on, they find two of the harpoon ships in the whaling fleet before they've killed a single whale. They are now set up for their most successful campaign ever.

After engaging the harpoon ships using the small boat teams, Paul makes the call to abandon the harpoon ships and go in search of the factory vessel. After a few hours of sailing, the tables have turned - two harpoon ships begin tailing Sea Shepherd.

Tailed by a harpoon ship, the Steve Irwin enlists the help of the Gojira in an attempt to break free. Meanwhile, the Bob Barker crew spots a large blip on their radar, and believe it could be their ultimate target, the Nisshin Maru.

When damage happens to one of the small boats, and the Bob Barker is 5 hours away, the crews realize they will have to spend a night at sea. But the crew is wet & freezing already & early symptoms of hypothermia begin to set in.

The Bob Barker desperately searches for their 2 small boat crews who were stranded at sea following a daring mission. The Gojira locates the whalers' refueling vessel & Locky plays a dangerous game of "chicken" with the massive ship.

New Zealand's Navy contacts the Steve Irwin about a distress signal where 5 crew members from a Norwegian sailboat have gone missing. The Sea Shepherds must risk their lives in a dangerous mission to find the missing mariners.

As the first leg of their campaign comes to a close, the Sea Shepherds battle physical & mental exhaustion, especially pilot Chris Aultman. Thanks to an anonymous tip, the Steve Irwin finally locates the whalers' factory ship.

The Bob Barker & Gojira launch an ambitious assault on the harpoon ship that's been following them & manage to disable the whaling vessel. Free of its tail, the Barker continues searching for their ultimate target, the Nisshin Maru.

After months of grueling searching, the Sea Shepherds have found their ultimate target, the whaler's factory vessel. But the behemoth factory ship is intent on escaping from the carbon-fiber Gojira in the deadly Antarctic ice.

Captain Paul Watson's crew of volunteers refuses to back down from the whalers, vowing to follow the fleet to the ends of the earth. Finally, after 30 years, Watson sees his life's work paid off with the ultimate victory.

After 7 years of intense battles, the Sea Shepherds believe they have finally driven the Japanese whaling fleet from the Southern Ocean. But Japan promises to return to Antarctica to resume its hunt & the stakes are higher than ever.

The crew of the Steve Irwin spot a ship on the horizon that they suspect is the Japanese whaler's factory ship. Meanwhile, already short on fuel, the Bridgitte Bardot is struck by a rogue wave and her crew prepare to abandon ship.

The terrified crew on the damaged Brigitte Bardot issue a distress call, but help is still 20 hours away. As raging seas continue to pound the fragile craft, the frightened crew fears they will not survive the night.

With the Japanese fleet's security vessel looming on the horizon, the captain of the damaged Brigitte Bardot orders his crew to evacuate the boat. In Antarctica, the Bob Barker deploys the small boats team to disable a harpoon ship.

The exhausted crew of the Brigitte Bardot scramble to evacuate the ailing vessel. And Captain Paul Watson goes on the offensive, sending a team to board the heavily armed security vessel the Shonan Maru.

With three activists aboard the Japanese security vessel, Captain Paul Watson hopes the media frenzy will force the Shonan Maru 2 to back off. Meanwhile, the crew of the Steve Irwin are plunged into their most violent battle yet.
