In order to produce a unique work in the photography competition, female college student Ying Jia persuaded her brother Xiao Shan and classmate Liu Lin, who are also photography enthusiasts, to go hiking in the Junggar Basin, waiting for an opportunity to shoot ideal works. To Ying Jia's surprise, they accidentally photographed a poaching gang killing red deer during the shooting process, and were hunted by poachers. After getting rid of the poachers, Ying Jia and the other two fled separately and agreed to meet at the camp at night. As a result, Xiao Shan and Liu Lin fell into the hands of poachers, and Ying Jia was caught by a branch when she rolled down the cliff and survived. Captain Liu of the Anti-Poaching Brigade of the Junggar Basin Nature Reserve and young volunteer Ma Qiang found Ying Jia in a trance during the patrol and rescued her to the protection station. Captain Liu arranged Ma Qiang to take care of Ying Jia, and he and Xiao Li went to look for Xiao Shan and Liu Lin. Frightened, Ying Jia was unwilling to believe anyone, and took the opportunity when Ma Qiang fell asleep to secretly leave the protection station and go to the camp to look for her brother and Liu Lin, but was forcibly pulled back by Ma Qiang who caught up halfway. Ying Jia narrated her experience to Ma Qiang. At Ying Jia's plea, Ma Qiang decided to accompany Ying Jia to go out and search. Captain Liu and Xiao Li encountered poachers in the desert and had a gunfight with them. Because they were outnumbered, Captain Liu withdrew from the gunfight to the protection station and asked for support. At Ying Jia's insistence, Ma Qiang followed the traces left by the poachers all the way, but was ambushed at the poachers' den, the car was blown up, and Ying Jia was captured by Lao Liangzi who came to collect the goods. When Lao Liangzi was trading with the poachers, Ying Jia was almost thrown into the mine. At the critical moment, Ma Qiang arrived, rescued Ying Jia, and told Ying Jia the whereabouts of Xiaoshan and Liu Lin. Inadvertently, Ma Qiang discovered that there were many internal conflicts in the poaching gang, and took the opportunity to steal the poachers' antelope wool. With the help of Ying Jia, he rescued Xiaoshan and Liu Lin who was injured in the leg. Sure enough, the poaching gang had an internal conflict during the transaction, and Lao Liangzi was killed. Ying Jia and others took advantage of the chaos to drive away with antelope wool and a password box containing one million yuan. The cunning poacher shot through the car's fuel tank and led the bandits to pursue them all the way. At this time, the rescue team organized by Captain Liu had already set off. Following the road signs left by Ma Qiang, Captain Liu chased the poachers' den. In the vast saline-alkali land, Ma Qiang and his four companions abandoned the car with no gasoline and moved forward with difficulty in the Death Valley. The poachers eventually caught up with them. In the contest with the poachers, Ma Qiang and Ying Jia were quick-witted and turned from passive to active. Just when the poachers tried to make a last-ditch effort, the rescue team led by Captain Liu drove away. A month later, Ma Qiang returned to the Anti-Poaching Brigade of the Junggar Basin Nature Reserve, and Ying Jia signed up to join the "Youth Volunteer Environmental Protection Action" program and became a volunteer of the Junggar Basin Anti-Poaching Brigade.
