The near future. Scotland has been left devastated by a plague that has
swept the country. The scattered population struggle to survive from day
to day. And the blame for this pandemic falls squarely on 'witches' -
seemingly ordinary people with extra-ordinary powers- who are hunted
down and forced to stand trial by government sanctioned witch-hunters.
Thomas Mackie is one such witch-hunter and, alongside his dog Dex, he
hunts down witches in order to save enough money and buy his way to a
better life, far from the poverty and devastation. But things take an
unexpected turn when Mackie's latest target- a witch called Miranda Lee-
blackmails him into helping her act out a dangerous plot to cure the
plague, once and for all.
