Ocean Warriors meets a range of fascinating characters that have answered the call to protect our seas, watching as they use innovative, direct-action tactics. We see stories of courage, conflict and change – from the Antarctic’s remote Southern Ocean to the coral reefs of Tanzania and the vast tuna fisheries of the Western Pacific. Climb aboard and set sail for the watery front lines as a global coalition of activists, campaigners, scientists and investigative journalists prepares to stare down poachers, tear up illegal networks and bring these modern-day pirates to justice.
