Snow mountain herder Sang Ning uses her experience to predict an avalanche and save Shen Ning, rejects the marriage arranged by her adoptive parents, and joins the ski resort safety team. Detecting falsified safety reports and with her old ankle injury unearthing secrets, her investigation uncovers the covered-up truth of the snow disaster from twenty years ago, confirming she is Shen Zheng's lost true heiress. Refusing an idle wealthy family position, she holds the safety veto power for the snowy region project and remains steadfast in the snow mountain rescue cause.
