The highlight of Ellis and Beth's year is their annual holiday to Sorrento in Italy where they meet with their regular 'gang' to enjoy good food, good company and certainly a restful time. This year is going to be different because this is the year when the Volcano Vesuvius is about to erupt and provide them with the most remarkable holiday that they have ever had. As the death toll mounts, Ellis and Beth are given the opportunity to show how they can really help in a crisis.
