Set in the Pacific, 1942, a Japanese ship transports prisoners of war to occupied territories as slave labor. After being torpedoed by allied submarines, a Japanese soldier and a British POW are stranded on a deserted island, but soon discover they are not alone. They are being hunted by a ferocious mythological creature, the Orang Ikan, a human-fish hybrid. Unable to communicate in each other’s language, the two mortal enemies must come together to survive the unknown.
