But one animal not on their spaceship's manifest is Kennedy's dog Chaser. Unable to part with his beloved Chaser, Kennedy smuggles the Labrador Retriever onto his father's ship.

Join Kennedy, Chaser, and the entire crew of Trinity Base as they travel billions of miles from home on an adventure as big as the universe, and find out just how far one boy will go to save his best friend.
