A group of city dwellers arrive on the Isle of Skerra to view the local lighthouse, which is up for sale. Young lovers Lana and Gregor, unhappily married husband and wife Bill and Joan, and businessman Tom all have their sights set on the unusual property and are met by lighthouse owner, and local oddball, Frances McGilvary.

However, what they don't realise is that all who set foot in this lighthouse are cursed. And before the night is out, they will have swapped their superficial city worries for an altogether bigger dilemma - how to escape the malevolent presence stalking West Skerra Light.
