A mysterious shadow walks the corridors. It goes from room to room, and sometimes leaves with someone in its arms, taking them to the land of dreams. Until one day a patient at the hospital―a young child―speaks to the shadow, offering it a drink of water. The child is fearful at first, but as he gets to know the shadow through their conversations, he realizes that she has feelings of her own. So begins a great friendship between an unlikely pair: a young child, and Death.
