Out of the syringe oozes a sticky yellowish liquid that magically turns into two sinister-looking men. These are the opening images of this chilling animation film, in which two chimney sweeps clear all the memories out of their victim's brain. Fearsome puppets inhabit a world of strange objects. What goes on in a man's head?
