In order to pay off the debt, I took on the high-priced job of live streaming a sleep trial in a haunted house. At twelve o'clock in the middle of the night, the old landline phone in the living room suddenly rang wildly, and the caller ID - the landlady who died here three years ago. The live broadcast room exploded instantly, and I picked up the call, only a cold cry for help came from the receiver. From then on, I was involved in a carefully arranged death mystery. Every step I took was getting closer to the truth and closer to the murderer.
