AFTER DEATH

Researchers at a remote jungle island outpost discover the natives are practicing voodoo and black magic. They kill a local priest (James Sampson), who has opened a gate to hell in retribution for tests that were being performed on locals (including his daughter who died of cancer). This portal causes the dead to rise and the researchers on the island are killed, except for Jenny (Candice Daly), the daughter of a scientist couple. She escapes, protected by a magical necklace charm given to her by her mother shortly before her death.

She returns years later as an adult with a group of mercenaries (Tommy, Dan, Maddis 'Mad', Rod, and Rod's girlfriend Louise) to try to uncover what happened to her parents. Shortly after arriving at the island, their boat's engine dies, stranding them. The mercenaries encounter their first zombie then Tommy, for some reason, runs the zombie down and starts pummelling it. He is subsequently bitten and starts turning. Meanwhile, elsewhere on the island, a trio of hikers – Chuck, David, and Valerie – discover the cave that leads to the underground temple where the hellgate was originally opened. After accidentally reviving the curse that raises the dead, said dead return to kill any who trespass on their island. The zombies kill David and Valerie while Chuck escapes.

Jenny and the mercenary group take shelter in the remains of the old research facilities' medical quarters, they are soon joined by Chuck (Jeff Stryker), the only surviving hiker. Arming themselves with weapons left behind by the long-dead research team, they make their stand as the dead once again rise. Louise is turned into a zombie by a bite from Tommy. She then turns Rod, who becomes our first gun-wielding zombie. Rod bites Mad - resulting in him becoming bed-ridden and later turning into a zombie. Still armed with his assault rifle, Mad shoots Dan repeatedly - mortally wounding him. Surrounded by zombies, Dan blows up the facility via a stockpile of grenades that appears suddenly, while Jenny and Chuck flee. They stumble upon the cave/temple again, where the zombies appear and attack. Chuck is killed, as Jenny throws her necklace charm into the hellgate to 'sacrifice her soul' and ends up being transformed into a zombie.

Jenny and Chuck attempt to end the zombie menace by returning to the temple, but Chuck is killed and Jenny, sacrificing her magical necklace, is transformed into a zombie.

The film concludes with the notion that the curse cannot be easily broken—Jenny’s sacrifice fails to close the hellgate, and she herself succumbs to the undead fate. This bleak ending seals the cycle of vengeance and supernatural retribution unleashed by meddling with forbidden forces.
