This is a strange one, part Mad Max 2, part LOTR, part end of the world disaster movie. The story while interesting is totally unbelievable. My mistake some miners are digging a hole into a dragons cave, the dragons take over the world and kills almost all humans.
Only a few are left among them the one that first saw the dragon as a kid.
Although the story is basically utterly crap. It is not too bad a watch actually.
