The cold-blooded shooting of Julian Tremayne in his manor house home on Bodmin Moor triggers a chain of terrifying events. The police inform his two sons that their cousin, Emily has been badly injured in a car accident which leaves her suffering from total amnesia. Upon her discharge from hospital she is taken to the family home in order to convalesce. But after the reading of Julian's will it soon becomes apparent that there is a real hatred between the two brothers. The nightmare escalates at the annual Halloween Ball when the legend of the Black Buccaneer becomes a frightening reality. Not only is there indisputable proof that James will stop at nothing to gain revenge - possibly even murder - on Emily for something which happened ten years ago, Emily is haunted by the fact that there may be serious flaws in her own character.
