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. When they arrive, they find the place under siege by some gunmen. Sek pitches in to help out, and to return the favor, Luang Kosit brings Thongchai and Sek to his home and offers them a place to stay.
Luang Kosit's daughter is Chonlada and she thinks she can help Sek determine where the meteorites fell. They contact the local "sea clan", where Chonlada had made friends with the chief's daughter, Sarai.
Meanwhile, a male friend of Chonlada's becomes jealous of her time spent with Sek, and while lamenting over the situation with some other friends, the group breaks out into song to chide him, while he voices his heartfelt desires.
