Four Kids, Three Cats, Two Cows, One Witch (Maybe)

Beverley, a bit of a snob, cooks up a plot to visit the island off the coast. She manages to convince the somewhat cautious Elizabeth and her slob of a brother, Gerard, to come along. A surprise companion is Kevin, the cool guy who works in the local shop. This motley crew must find ways to support each other and put up with one another's shortcomings, when they become stranded on the island and encounter a strange inhabitant.
