In the not-too-distant future, a group of four foster children stumbles upon an extraterrestrial creature that journeys across the universe, gathering the last remaining animals of species on the brink of extinction. After rescuing the last elephant, a mishap leads to the alien’s spacecraft crashing on the children’s farm. It falls to Johnny, Tabby, Finn, and Julia to repair the alien vessel and ensure it, along with its precious cargo, departs Earth before government officials can track them down and apprehend them.
