Standing on the beach watching the early morning-mist roll in off the sea, Fin is thinking about the day when he can escape to the mainland. His sister got away, but no one has heard from her in two years. Fin's thoughts are interrupted by the sound of a car on the bridge above him. He hears doors slam, voices, a scream and then, for a brief moment, he glimpses a figure falling through the fog. It's a young girl and she dies in Fin's arms.

Did the dead girl jump or was she pushed? Sceptical of the official suicide verdict, Fin is determined to find the truth, a hunt that will lead him closer to his missing sister and to a shocking secret at the heart of his island community.
