A Scottish tale of terror.
When Sergeant Dave Wilkes and his constable, John Campbell, are called out to a remote island, it is to investigate a simple case of sheep worrying, what they think is a routine job. But upon arrival at Leita, they find the community to be empty, the shops and houses lying quiet. Before too long, they find disturbing evidence of violence and mayhem.
They get some of the story when they find three survivors holed up in a farmhouse, but the tale they tell is almost unbelievable - a grisly story of ritual cannibalism, blood sacrifice, and a ram's skull that makes its wearer both invincible and irresistible.
Soon they are in a fight for their lives, as the ram takes control of the island.
Can they stop it and prevent it from spreading?
Or will the ancient magic of the ram prevail and take its bloody promises to the mainland, and to the town that is waiting to be shown its glory?
