In a catastrophic frozen‑wasteland year, four‑year‑old orphan Ailia is transported to a modern‑day city by a bone‑carved wolf‑tooth necklace left by her mother. Starting out by scavenging fried chicken, she brings food, clothing, tools and medical knowledge back to the nearly‑extinct Chishi Tribe. She exchanges tribal bone carvings for modern supplies, leads her people from starvation to prosperity, and resolves old tribal hatreds with kindness. She finally becomes a top‑tier surgeon and discovers a mysterious blood‑tie link between the two worlds.
