When Keeker and Plum take a family road trip to upstate New York, Keeker is sure it will be the best family vacation yet. (Plum, on the other hand, is not convinced!) Keeker is excited to splash in the neighborhood pond and ride ponies in the country with her cousins. What she doesn't know is that the nearby town of Sleepy Hollow holds a mystery that will make this a very memorable family vacation!
