Nonton Shadow Island (2023) Sub Indo di MovieXXI

David, an aspiring meteorologist, follows his late father's footsteps in the Swedish military. After stumbling upon what's left of his father's work, David sets off to a desert island in the Barents Sea - the one place which may hold the truth about his father's passing. Confronted by strange lights in the dark, eerie radio disturbances, and a hidden cave, David begins to question whether or not he's really alone on the island. Suddenly, a female voice calls out over the otherwise silent radio - a stranger trying to reach David. Little does he know, his search for truth is about to descend into a much larger conspiracy.
