Meet Isserley, a female driver who cruises the Scottish Highlands picking up hitchhikers. Scarred and awkward, yet strangely erotic and threatening, she listens to her hitchhikers as they open up to her, revealing clues about who might miss them if they should disappear. Under the Skin takes us on a heart-thumping ride through dangerous territory—our own moral instincts and the boundaries of compassion.
