15-year old Marie & 6-year old Shaun are neighbours. Whilst Shaun goes on hunting trips with his father Filthy, a secret den in the hill has become Marie's refuge from a world she is finding increasingly difficult to cope with. One night while Marie is babysitting for Filthy, Shaun suddenly dies in her care. As Filthy's grief threatens to overwhelm him, Marie becomes aware of another presence. It follows her from the hill into the city & it won't leave her alone. It wants something from her. Is it the spirit of Sean? Or her unresolved past creeping into her present & distorting her perception of reality?
