The film takes us to the Mediterranean, following volunteers of the NGO Sea Shepherd over several months in their fight against pollution, illegal fishing and poaching. A struggle with no end in sight, such is the scale of the task.

The documentary immerses us in the lives of Sea Shepherd members on a campaign, offering an unprecedented encounter with these men and women, entirely committed to their cause. Over the course of the film, we discover their enthusiasm for action, their desire to accomplish something tangible, and we witness the real day-to-day work of the NGO. Far from the image conveyed by the press and social media, the organisation continues to hunt marauders, but now does so in collaboration with the authorities to hold polluters and poachers to account.
