A very bad movie. Zombies become slow moving, crawling worm-like creature, looked just like Michelin Man or savege-like people.
The story was about a little boy bringing his mum, who was ill and unwell to see a Doctor who lived in the Zombie land. Surviving after several encouters with Zombie, they finally met with the Doctor, only been told that his mum got terminal cancer (this was already around 3/4 of the movie). His mum died in the same night and they carried out something like ritual, that is to scrap everything from the corpse until the skul is remained. The doctor then asked the boy to choose a place for his mother's skul before they were attacked by Savege-like zombie.
The boy stroke an arrow with morphine on the zombie and saved the Doctor and went back to his own village to live on his own.
