When an 18th century cleric, Rev. Heatly Smythe, is appointed to a new rural Parish, he finds his faith tested by local superstitions surrounding a strange mound in an ancient woodland. Being an academic, Heatly has little time for the local superstitions, and begins to ruminate about the true nature of the so-called 'Devil's Mound'. In an attempt to rid the parish of its 'blasphemous beliefs', Heatly endeavours to prove that the mound in question is merely an ancient burial sight of historic importance. Led by arrogance and a blind self-conviction, Heatly Smythe finds himself confronted by local friction, tragic circumstances, and an illusive individual that begins to haunt his every step. Loosely based on a chapter from the 'smash hit' novel 'Skendleby', by Nick Brown OBE.
