About the title
Sarah and Fergus move to the wild coast of Scotland to start their life over after the tragic death of their young son. Fergus writes a blog about excavating ancient burial sites. He finds and digs up a Viking skull, unwittingly releasing an evil spirit that had slumbered for centuries. The Viking spirit possesses Sarah, and Fergus calls the local priest to help Sarah and perform an exorcism, but the ritual doesn't work. Fergus has to turn to Mungo, a local resident well-versed in medieval legends, and ask for his help in fighting the cruel spirit that has possessed his wife.
