Adelle's worst fears are realised when, days into a trip aimed at reuniting her daughter Sarah, with her estranged father, she is swept out to sea and drowned. Haunted by visions of Sarah, Adelle learns of a local legend - a place called The Dark - a land of the dead that is a distorted mirror image of the real world. The legend dictates that the dead can be returned from The Dark if the ultimates sacrifice is made - one of the living for one of the dead.
