Plot

Anthropologist Max Scarry (John Bach) mysteriously vanishes following his voyage to the island of Fjordland as part of his study on the reclusive Kiwi tribe Huwera Maori. The police believe him to be guilty of murder, after they find a woman's corpse in his island retreat. Max's spouse Ruth (Darien Takle) accompanies her brother-in-law Edward (also Bach) in uncovering the truth. They venture into the eerie island and are haunted by ghastly happenings. Finally, Edward snaps under mental pressure and his brother, apparently having died, possesses his body during a supernatural Huwera Maori procession.
