The notoriously hard-drinking, backstabbing Stonebridge Radio crew are having their Hallowe'en party on Winkle Island, rumoured to be the most haunted place in Northern Ireland. Unfortunately, Adam and Colin are there too, having accepted an easy pay day from Colin's event organising mother. At dinner, a shocking announcement is followed by an even more shocking murder, and the theft of a priceless Firefly necklace. To top it all, thanks to a raging storm, everyone is trapped on the island. Now, faced with devious radio presenters, a strange tour guide, and a rampaging murderer, Adam and Colin are back in business.
