In Part 1 of the two-part Season 3 finale, Bethune attempts a citizen's arrest of a Japanese ship's captain. Meanwhile, the Bob Barker's reconstructed engine fails, leaving the crew stranded.

As the Sea Shepherds approach the Nisshin Maru, they are suddenly surrounded by four whaling vessels. Suddenly, one of the Japanese vessels moves in dangerously close, and as the deck crew quickly braces themselves, the ships violently collide.

The Sea Shepherds refuse to be bullied by the Japanese fleet even though they're out numbered. The deckhands repel over the side of the ship to assess the damage from the collision and realize that there is a gash in the steel hull and water is pouring in.

The Sea Shepherds employ a new strategy in their campaign against the Japanese whalers.
