Sadness at the End of the Play

An empty coffin, five people, a funeral on a snowy mountain. A painter, a female star, a doctor, an entrepreneur, and a high school student - five people received anonymous obituaries and were deceived into entering a snow mountain B&B by an email saying "Shen Mo passed away." The road was blocked by wind and snow, and there was no signal. They were trapped in this isolated wooden house. The coffin is empty. There are no bodies. The "dead man" in the video said: I left a legacy for myself. If you find it, you will know who I am. But the truths they found were more outrageous than the others... After the drama ends, where will the final stand-in go?
