Adelle decides to take her daughter Sarah to Wales in the hope that the child can rebuild a relationship with her estranged father, but only days after their arrival tragedy strikes when Sarah is swept out to sea and drowned. Tormented by visions of her dead daughter Adelle hears of an ancient legend, a passage way back from a land of the dead should one of the living take the place of the already taken. The Dark is a creepy psychological horror, a wee bit daft admittedly, but there's a good cast and it's not short on atmosphere.
