People throughout history, before they died, have seen something...strange. They have seen ghostly doubles haunting their steps, foretelling their doom. These things are called doppelgängers, and while they mean something different now - basically someone that looks like you - their folklore origins are something far more ominous and sinister. This episode is about the shadowy creatures of ill omen that follow us all, and the famous historical figures that have seen theirs before they met their end.
The creature of the week is an extended, creepy story of a creature from Japanese folklore, and a solitary priest that became lost in the mountains.
