While on an adventure in the forest, Pete (Oakes Fegley), along with his mother and father, are involved in a terrible car accident, leaving Pete alone in the middle of nowhere. He journeys deeper into the forest where he encounters Elliot, a large, green dragon. With no reason not to accept the kindness the dragon showed, Pete decided to go with him, marking the start of a long friendship. Six years later we find Pete and Elliot living peacefully in the deep of the forest, only to learn that humans are about to discover their home.
