It's 1984, and Daniel Knox is on the run. He's spent his entire life evading mysterious creatures that are disguised as everyday people - the ones he calls 'Shadows'. Preying on humans in secret, the Shadows are an enigma even to Daniel. But he knows one thing for sure - the Shadows' true nature can't be seen by anyone but him. As he seeks refuge in a remote mountain community, Daniel crosses paths with a traveller who is investigating the disappearance of her sister in the same town. Gradually, the secrets begin to unravel - and for Daniel - life will never be the same again.
