A field trip to Discovery Island means three whole days off from school. It's a kids's dream -- or is it a nightmare? When a huge storm blows their ferry off course, the Baily School Kids find themselves shipwrecked on an isolated island with strange vampire-like inhabitants. Mrs. Jeepers doesn't seem too worried. In fact, she seems to know her way around the island very well. Could they be stranded on Vampire Island? The Bailey School Kids are going to find out!
