A gang of rogue Whalers act as the main antagonists of Iceland's first exploitation horror, known as Harpoon - they are made up of a sadistic mother and her two sons, in a manner very similar to horrors such as Mother's Day, Texas Chainsaw Massacre and the Hills Have Eyes.

The Whalers inhabit an old and decaying whaling ship, having long fallen into poverty and madness the family exist in isolation and lure in victims in order to kill them and presumably devour them, however like many horror villains they love to torture their victims before actually killing them.
