The people featured on the show risk their lives for their cause, but not everyone will agree with their opinions or their tactics (which include stink bombs and using other, non-life-threatening ammunition against the crews of ships who claim to be killing whales legally for research). Often the activists' mere presence is an act of breaking the law, and they feel right in destroying personal property, avoiding arrest, and inflicting bodily harm on their opponents if it means saving whales.
Whales are harpooned and dragged aboard ship (some blood). Some scenes show them being dismembered and their meat cut up for sale. Confrontations between the Sea Shepherds and the whalers often turn violent, and the crews hurl stink bombs and tear gas grenades at each other. Shootings, hostage situations, threats of terrorism, and the harsh elements at sea put the players in constant danger.
Common use of "hell," but anything stronger ("s--t," "ass," "f--k," and the like) is bleeped.
