一个工人正在打扫卫生，突然一声巨响把车子砸了一个大坑，等警察来到现场的时候发现车顶严重变形但是周围并没有高大建筑，艾伦认为是对面大楼坠落的死者，车子因为受到冲击力打滑到了这里。艾伦为了证明自己的猜想来到了对面大楼前，果然看到璃碎片认定这里就是第一案发现场

与此同时，大楼内的一间电梯里面发生诡异的事件。五个身份各异的人正在乘坐的电梯突然卡在十三层，监控室察觉到异常赶紧请修理工去查看。奇怪的是修理工发现电梯并没有异常，监控室也听不到电梯里面的声音。因为修理工重启电梯导致熄灯，电梯的灯光突然闪烁，保安看到监控室有一个奇怪的鬼影，等到灯光亮起来的时候，电梯里贵妇的后辈被划出一道伤口，因为卷毛身上有血迹被大家怀疑，等到灯光再次灭掉又亮起来的时候，卷毛的脖子上被插着一块玻璃。

A worker was cleaning, and suddenly a loud noise smashed the car into a big hole. When the police came to the scene, they found that the roof was seriously deformed but There were no tall buildings around, and Allen thought it was the deceased who fell from the opposite building, and the car skidded here due to the impact. Allen came to the opposite building in order to prove his conjecture, and he saw the broken glass and decided that this was the scene of the first crime

At the same time, something strange happened in an elevator in the building. The elevator that five people with different identities were riding was suddenly stuck on the thirteenth floor. The monitoring room noticed something abnormal and asked the repairman to check it. The strange thing is that the repairman found that there was nothing abnormal about the elevator, and the monitoring room could not hear the sound inside the elevator. Because the repairman restarted the elevator and turned off the lights, the lights of the elevator suddenly flickered. The security guard saw a strange ghost in the monitoring room. When the lights came on, a wound was drawn on the younger generation of the noble lady in the elevator, because there was blood on the curly hair Being suspected by everyone, when the lights were turned off and on again, a piece of glass was inserted around Curly's neck.
