Black Coral Episode 4

Marine biologist Narathon’s mission to restore Thailand’s reefs takes a dark turn when he learns of a pristine coral hidden near Skull Island, a place cursed by deadly whirlpools. Joined by photography professor Prachaya and gifted dive photographer Kaimook—whose past work drew the obsession of Narathon’s estranged tycoon father, Phum—he uncovers troubling secrets. Phum’s interest, and his alliance with the enigmatic Sairung, hints at a plot involving the islands’ land and waters. As Narathon dives deeper, he’s caught in a web of ghostly legends, hidden crimes, and the mysterious Sarai—whose haunting connection to the reef could mean salvation… or death.(Source: BEC World)~~ Adapted from the novel "Pakarang Si Dam" (ปะการังสีดำ) by Pradit Kaljareuk (ประดิษฐ์ กัลย์จาฤก).
