• its about some "beast" or "ghost" being trapped in a certain tomb for the good of the general public
• and this "beast" have a brother who wanted to free him so that they can rule the world or something like tat...
  
• and the way to the tomb only the female lead can remember cos her father is person that build the tomb and brought her there when she was very very young
  
• along the way the female lead lost her memory and was being brought up by the killer of her father just to make sure she don't recall how to get to the tomb
• they went to someone who is an outcast of their "tribe" to find out more details of how to get to the tomb
• the key to the tomb is all the while on the female lead.. its some necklace or something (can't exactly remember)
