Captain Nolan is an Irish Canadians who catches marine animals in order to pay off the Chattel mortgage on his boat and eventually return to Ireland. Nolan's crew is currently looking for a great white shark for a local aquarium, but a scientist named Ken is targeted by the shark. An Killer whale intervenes and kills the shark, saving Ken's life. This switches Nolan's target to the orca. Later while hunting with his crew, Nolan tries to capture what he believes to be a male orca, but mistakenly harpoons a pregnant female. Nolan and his crew get the orca on board, where she subsequently Miscarriage. The captain tosses the dead fetus overboard as her mate looks on, screaming in anguish.
