Stella and Dot are two sisters embroiled in an exciting quest to save endangered animals on Earth and bring them to the mysterious Planet Beatrice, where woolly mammoths roam and children make the rules. While some of the children are friendly, others become their mortal enemies and plot against them as they learn how to fly with eagles and embark on an adventure of a lifetime into the far reaches of outer space. With the threat of the bushfires in Australia looming, the girls must figure out how to work with these strange children and harness the power of the magic ship, the Salvager, to save as many animals as they can.
