In the 1990s, Mazhi County on the Qinghai-Tibet Plateau relied heavily on agriculture and animal husbandry, and it once sank deep into poverty. Nearby lay the Uninhabited Zone, Bolamula, rich in mineral deposits and wildlife resources, which attracted poachers and illegal miners who slaughtered and exploited for huge profits. With the support of County Chief Lin Peisheng, Deputy County Mayor Duo Jie established a Mountain Patrol team. After witnessing the horrific slaughter of Tibetan antelopes, Duo Jie devoted himself to environmental protection. Among the patrol team, the young policewoman Bai Ju became Duo Jie's destined variable. She was an orphan adopted by Zhang Qinqin, a doctor aiding Tibet, and the youngest daughter of the Bai family, fearless and bold by nature. After entering the uninhabited zone, Bai Ju quickly matured, forming deep bonds with the patrol members and falling in love with newspaper reporter Shao Yunfei. They established a nature reserve together, only to face Duo Jie's disappearance and the disbandment of the patrol team on the eve of success. More than a decade later, Bolamula has regained its tranquility, but illegal coal mining occurred again. Bai Ju reunites with everyone and pursues the truth behind Duo Jie's disappearance while conserving the environment. In the end, they restore the hero's good name and continue to safeguard the Qinghai-Tibet Plateau.
