Hillary is a human girl living in Stonehenge in prehistoric times. She is hailed as Queen of the Dinosaurs, as she protects and leads them. However, while exploring one day she is caught in a time slip. When asked to return to Stonehenge, she is instead transported to the concert halls of 1970s progressive rock group Stonehenge, wherein she becomes enamored with them (particularly their bassist Andy) and now must adapt to 20th century life.
She has a rather brutish nature and tends to end up in fights, usually finishing them for the sake of other kids. Her strength intimidates many, including Andy.
