Patience is the virtue of the gamekeeper. Waiting for the right moment to strike anything that threatens the balance between man and nature. He is nature's remedy to man's disease. Brock lives a quiet existence as Gamekeeper on a secluded Scottish estate, until paramilitary mercenaries storm the estate and kill Jonah Morgan - the owner and Brock's friend. Now, Brock faces his dark past and the events he had sworn he'd forget. Obliged to avenge Jonah's death, Brock must leave his tranquil life and journey deep into an unfamiliar, urban underworld. But as he gets pulled in deeper, it's difficult to tell who has more power, Brock, the man, or the animal within.
