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.

When a massive target is detected on their radar, Sea Shepherd sends out their new helicopter pilot to ID the vessel. But as the helicopter reaches the limits of its fuel range, it abruptly disappears, crashing into radio silence.

After months of frustration, the Sea Shepherd finally finds its target, the Nisshin Maru. Now they must run an 8-mile gauntlet blocked by two harpoon ships aggressively defending their mother ship.

The Sea Shepherd embarks on its 10th anti-whaling campaign, but for the first time they are without Captain Paul Watson. Peter Hammarstedt takes the reigns as leader, where a single misstep could cost hundreds of whales their lives.

With a brutal storm threatening to strike & crew members refusing to obey orders, campaign leader Peter Hammarstedt finds himself struggling to maintain control. With the Japanese harpoon ships looming, the campaign may be in trouble.

The battle to stop whaling reaches its apex as the Bob Barker & a Japanese harpoon ship collide. Sea Shepherd must track the whaling fleet by helicopter, but when a blizzard blocks communications and freezes instruments, hope fades.

Bobo, Cliff, Matt and Ranae travel to the forests of northern Georgia to examine footage of what could be a Bigfoot running across the road.
