Watch Porno Holocaust

Porno Holocaust is a pornographic horror film from 1981 and begins with a cadre of scientists being brought to an island that served as a nuclear test site in 1958 so that they might investigate mutated animals and even sightings of a monster. The scientists soon discover massive crabs with an unseen creature soon stalking and spying on them. Some time later, Professor Keller decides to go for a swim after making love to his wife, only to be drowned by the monster, which then assaults and murders the professor's wife.

Back at the main camp, two crew members from the ship decide to collect fruit only to be followed and killed by the monster. The other researchers hear the attack and go to investigate. The monster bides it time and eventually captures Annie, dragging her to its cave. It is within this cave where Annie finds a journal, revealing this creature to formerly be a native named Antoine Domodurio. Antoine survived the atomic bomb tests which only mutated him instead of killing him like his family.

The following day, the party discovers the crew members' bodies and that their boat is missing. Captain Hardy hunts for Annie but finds "Benoit" instead. Benoit is a reporter who followed the researchers, explaining that his injuries were from an ape man who is holding Annie hostage nearby. Back at camp, Antoine kills Professor Lemuan, then assaults and kills Countess de Saint Jacques, with only Hardy able to rescue Annie.

Hardy manages to find Antoine's cave and frees Annie, but Antoine makes his presence known as they escape. Hardy fires a spear into Antoine's chest only for Antoine to rip it out and use it as a melee weapon against Hardy. However, Annie manages to distract Antoine by calling out his name long enough for Hardy to strike him down. With the threat dealt with, Hardy and Annie leave the island on Benoit's vessel.
