Five‑year‑old girl Lily touches an alien prehistoric totem in a museum and gets accidentally teleported to the primitive Greenwood Tribe on a wild planet 4.2 light‑years away from the Solar System. The tribesmen take her for a disaster‑bringer fallen from the sky and intend to sacrifice her. At a critical moment, Lily saves the dying tribal chief Draven with modern scientific knowledge. She then teaches the primitives to make fire by drilling wood, bake clay pots, and filter and purify salt‑brine to obtain edible salt. Later, she skillfully resolves tribal conflicts, leads the primitives to develop infrastructure and farming, and embarks on a tough yet joyful tribal‑building life on the savage planet.
