Su Wanxing, captain of a polar research team, is swept away by an avalanche to an ancient icefield and saved by Cang, chieftain of the Snow Wolf Tribe. Using modern science, she teaches the tribe ice fishing, fire-making with ice mirrors, warm housing and iron smelting. Once rejected as an alien witch, she becomes the tribe’s respected goddess. She and Cang grow close amid life-threatening dangers, facing Aya’s malicious frame-up, shaman oppression, and joint attacks from the Black Snake and Wild Bone Tribes. She helps Cang unify the tribes and establish the Snow Wolf Alliance. Yet she accidentally activates temporal power in a geothermal valley and returns to modern times. Only the wolf-tooth pendant on her neck witnesses that her icefield adventure was real.
