Things seem to be normal in an area of Thailand. But then Dracula is summoned to that region from Europe. He goes after a young woman. He has a bunch of dancing female vampire servants. Devils, zombies and some other weird creatures also show up.
Before her death, a grandmother gives her granddaughter a magical ring that'll give her dead spirit power over her. The spirit manifests itself when her head detaches from her body at night and flies away with guts dangling under it, seeking blood to drink or raw flesh to devour.
