Some secrets are buried too deep…and some will drag you down with them.
In “Black Coral,” marine biologist Narathon embarks on a mission to restore Thailand’s reefs, but his journey takes a sinister turn when he discovers a pristine coral site hidden near Skull Island, a location notorious for its deadly whirlpools. Teaming up with photography professor Prachaya and talented dive photographer Kaimook—whose previous work has drawn the attention of Narathon’s estranged tycoon father, Phum—he begins to unravel unsettling secrets. Phum’s growing interest, coupled with his alliance with the mysterious Sairung, suggests a deeper conspiracy involving the islands’ land and waters. As Narathon plunges further into the depths, he finds himself ensnared in a tangled web of ghostly legends, concealed crimes, and the enigmatic figure of “Sarai,” whose haunting ties to the reef could lead to either salvation or doom.
