Amy followed her friend Zhou Fan to explore Qiaotou Snow Mountain. Zhou Fan left without saying goodbye the next morning. Later, the police found Amy and asked about the situation, and Amy learned that Zhou Fan had fallen off the cliff and died. Amy's soft decoration design company received a hotel soft decoration project. Amy once took Party A's car and went to the construction site with its chairman Liu Xingming. While chatting on the road, Amy accidentally revealed to Liu that she had been exploring here and said that the people who came with her fell off a cliff and died. This aroused Liu Xingming's interest. Amy suspected that Liu Xingming and Zhou Fan knew each other. Liu Xingming kept showing goodwill to Amy and quietly insinuated whether Zhou Fan had left anything behind. Zhou Fan left behind a small bottle containing white powder and a USB flash drive when he broke up with Amy. Amy felt that the things left by Zhou Fan were unusual. Amy was curious about the cause of Zhou Fan's death, so she secretly launched an investigation. As the fog was lifted bit by bit, she found that all the clues seemed to indicate that there was a conspiracy in Zhou Fan's death. The hotel construction site in the Qiaotou Snow Mountain hidden some ulterior secrets.
