In 1947, a father and son set out on a glider flight over the Pacific Ocean, but powerful winds and a sudden cyclone carry them far off course into the remote southern Indian Ocean. Stranded on an uncharted island after surviving the storm, they face harsh conditions, dwindling resources, and a terrifying encounter with a massive, bird-like predator deep within the jungle. But the true horror arrives in the form of hovering alien orbs-Ralspheres-that freeze time and summon a red-eyed, reptilian humanoid who coldly extracts their souls and vanishes, leaving their lifeless bodies behind.

As the beasts consume what's left of the father and son, a lone white-tailed monkey retrieves the fallen pocket watch from the sand-an eerie token of a vanished expedition. Years later, whispers of that watch surface in Australia, hinting at a dark encounter between man, nature, and something far beyond our world.
