After a car accident, the modern female doctor Sun Ying traveled to the wild beast world and became a thin female "Ying" in the Black Wolf tribe who was regarded as a burden. She faced not only the harsh natural environment, but also the deep-rooted prejudice and contempt within the tribe. The villain's agent - the deputy leader "Scarface" who covets the position of leader, and the female "Li" who is jealous of her attention from the wolf king "Thunder", constantly question and sabotage her every attempt, trying to completely marginalize or even expel her. Sun Ying's fate is: if she cannot help the tribe solve the problems of food shortage, disease and cold protection before winter comes, not only will she, a "useless" female, be abandoned, but the entire tribe may be at risk of extinction due to hunger, cold and disease.
