Skeleton Island is an eerie place - deserted except for pirates' bones and a young girl's ghost. Scarcely anyone dares set foot on the haunted isle, which is why a movie company decides Skeleton Island is the perfect place to make a scary film. When mysterious events disrupt the filming and unnerve the crew, the company calls in The Three Investigators. But as soon as the boys appear on Skeleton Island, so does the ghost.
