1745 Wales is a land that time forgot. The burden of squalid poverty and the power of medieval superstition is writ large on the landscape as the adventurer, womaniser and dreamer Gruffydd comes to reclaim his birthright after the Jacobite Rebellion drives out George II. Hoping to deliver his people from the brutal control of a dissolute overlord, the local Squire Sir John Ffowlke, Gruffydd settles in the village of Cwmystwyth. Unrecognised, he becomes the local conjurer on whose magical powers the desperate villagers soon come to depend. Boldly, he fights for a vision of the future where they are free from the feudal chains that bind them.

But Gruffydd is surrounded by enemies. Charisma may not be enough to keep him alive, and if his people see through him, he may be faced with a bloody reckoning. The conflicting forces within the village of Cwmystwyth must be overcome if Gruffydd is to be able to unite the downtrodden community and guide its inhabitants towards freedom and a new life. Can any good come of a lie, however inspired?
