[1][2] Astronomer Professor Thongchai and his assistant Sek observe some meteorites falling and determine they struck somewhere in Southern Thailand.

They head for Ranong Province where they start their investigation at a potash mine owned by Luang Kosit.

They contact the local "sea clan", where Chonlada had made friends with the chief's daughter, Sarai.

The next night, the alien creature finds its way to the mainland and attacks a young couple, who then turn their death-ray eye beams on others.

Professor Thongchai examines a sample of the alien under a microscope, and eventually it is noticed that exposure to sunlight kills the creature.

More drama ensues as Chonlada and Serei go into the cave just as it is to be sealed, and Sek and another man need to scuba dive in to rescue them through an ocean entrance.
