The small Scottish town of Auchenmullan is dead, and has been for years. It sits in the shadow of a mountain, forgotten and atrophying in the perpetual gloom.

Forty-seven residents are all that remain.

There's nothing to do there, nothing to see, except for a solitary grave near the top of the mountain.

MAGGIE WALL BURIED HERE AS A WITCH reads the faded inscription.

But sometimes the dead don't stay buried. Especially when they have unfinished business.
