Oliver the cat lives in a house with a garden, a garden full of light and shadows, full of things that dance and flutter; a garden that comes to life in the moonlight and tempts the young cat to stay outside all night. And so he does. But Oliver's excitement soon turns to fear as he encounters the mysterious and scary sights and sounds of the dark garden. The garden is dark and wet and lonely -- and home is safe and dry and warm. Suddenly, Oliver decides that his owner might be frightened, too, and that it's his duty to go inside to comfort her. And so he does.
