Lin Sui used dumbbells to press the coffin, just to hear her late husband's breathing. But that day, she heard him crying: 'Don't move that wall! ' Chen Yan, the Feng Shui master who helped her build the wall, had blood and tears oozing from his left eye. She didn't know that there were three corpses buried in the wall. She didn't know that the hot soup provided by the housekeeper Zhou was both poison and soul-soothing soup. She didn't even know that her niece Su He's video contained the missing reporter Qin Jing's cry for help. When the dumbbell dropped for the third time, the wall cracked, revealing a small hand holding an old diary - that was not her husband's, but her sister who was pushed into the crack of the wall by her own hands when she was seven years old.
