The documentary follows the events that took place during ''Operation Leviathan'' in early 2007. The RV Farley Mowat, captained by Paul Watson and the newly acquired MY Steve Irwin, captained by Alex Cornelissen meet in the Southern Ocean. As they are docked side to side, material is transferred from the ''Farley Mowat'' to the ''Robert Hunter'' to build a new helicopter deck. After some time the ''Robert Hunter'' is able to find the ''Nisshin Maru'' and engages it. In the course, one of the Sea Shepherd's small boats with two men on board gets lost. Both Sea Shepherd vessels must abandon the ''Nisshin Maru'', which later takes part in the search for them. Finally after 9 hours, they are able to locate them and they are saved. Having lost the ''Nisshin Maru'', the ''Robert Hunter'' later finds the ''Kaiko Maru'', a spotter vessel for the Japanese whaling fleet. They engage the ship and during maneuvering through an ice field collide with each other, damaging both ships. As the ''Farley Mowat'' approaches, the Japanese vessel calls out a Mayday, stopping the Sea Shepherds from further engagement. As the film ends, we find out that there was a fire on the ''Nisshin Maru'', killing one worker and ending the whaling season early due to damage to the ship.
