The peace of Mildew Farm is shattered when two best friends are plunged into a deadly adventure of dark magic and monsters.
On a seemingly ordinary farm in the north of England, sinister events are unfolding. Two farm workers, Jacob, a serial daydreamer and would-be adventurer and Walter, a short mute, find themselves in trouble when Jacob breaks the rules set by the cruel farm owner, Grenville. The rule that no one is to talk to his beloved daughter, Eleanor. Only Jacob can’t help himself and after meeting her by chance he falls head over heels in love with her. Jacob knows his master's cruelty but is unaware of what is in store for him.
After somehow finding out his secret, Grenville uses dark and terrible powers to turn Jacob into a twisted and deformed scarecrow. To save his friend, Walter, who is the most unlikely of heroes, steals the scarecrow and takes it far away from the farm. But Grenville sets out to find and destroy him.
Having never lived away from the farm and the warmth of the barn where he slept, Walter soon finds himself lost, cold and alone. He now has to survive a death-defying ordeal on his quest to escape Grenville’s wrath and undo the spell put upon Jacob.
