Xia Meng (played by Chen Zihan), who just graduated with a master's degree, went to Thailand with her newlywed husband Chang Zai (played by Li William). On the way, they heard that Jinsha Valley was very beautiful. As a reporter, Chang Zai decided to take Xia Meng on a romantic trip. On the way to Jinsha Valley, Xia Meng saw a scarred face and was frightened. She was inexplicably knocked over by an off-road vehicle and almost died. Then Chang Zai fell into a trap again. Fortunately, a young man named Zheng Dalin (played by Tan Yaowen) rescued him. Xia Meng felt that Zheng Dalin and his lover Yila (played by Niu Mengmeng) had a subtle relationship and a suspicious identity, so she reminded Chang Zai to be careful, but Chang Zai was intoxicated by the beautiful scenery. The two teams of lovers decided to travel together. On the way, they learned that a pair of tourists were killed at the foot of the mountain and the local police were investigating. While they lamented the poor local social security, they also felt uneasy about being in a psychedelic jungle! Along the way, they met a mysterious sexy woman who came and went without a trace; a young man and woman who died a violent death; and the scarred man who had been following them... As the journey deepened, dangers were everywhere and they didn't know what kind of situation they were involved in. Suspicion, despair, and horror followed one after another, testing people's bodies and spirits again and again, and all this was just the beginning...
