There's a legend in Thailand about an American soldier's exploration of an
underwater world called the "Pearl of Naga". Though disappeared, it is said
to be full of treasures, including immortality and the power to any empire.
Camera, the queen of darkness, wants this power to control the entire world
but isn't the only one. An international organization and a group of vampires
are also after it. There is someone who knows the location but refuses to
reveal it. (IMDB)
