Ye Xiaoyan, Chen Yifan and six other college students who are about to graduate from a medical school in Beijing are preparing to travel to a scenic spot. The mountain road is rugged, the sky is dark and foggy, and the car actually broke into the forbidden area in the mountains. The sudden collision and the shabby scarecrow that fell in front of the car made everyone panic. The mountains were silent, and this dark land seemed to be brewing something. The engine failed, and several people had to walk forward, not knowing that what was waiting for them would be a catastrophe that they would never forget. The village was shrouded in mist and miasma. Ye Xiaoyan and her group were surprised to find that there were only women but no men here, and the villagers' evasive tone and indifferent rejection were even more incredible. Companions disappeared, friends betrayed, runaway boys... In the hot summer, everyone felt like falling into an ice cave. A word from the charming woman Wang Chunhua awakened them, and all the conspiracies seemed to point to the back mountain. Should they save their companions regardless of life and death, or escape from right and wrong? In the face of danger, they resolutely ran to the back mountain. What secrets are hidden in this famous "Widow Village"? Will the tourists see the light of day again or will they be buried forever in the village? Who is the real murderer behind the scenes?
