Police officer Zheng Qiang was ordered to investigate this case, and Zheng Qiang's journalist girlfriend Yu Xin met Xiao Ling, who was engaged in pornographic phone calls, in a restaurant for an exclusive interview. The boss Mei Shumin also took the opportunity to chat up. Later, the mysterious murderer confronted Xiao Ling and even threatened to kill her by phone. Xiao Ling brought friends to accompany her and threw away the fate of being raped before being killed. At this time, the police received a call from the arrogant murderer, leaving them at a loss. As Zhengqiang tirelessly studied the development of the case, the killer's palm had quietly reached out to Yuxin.
