Dawn the morning of the winter solstice, Yang Yuan's nine-year-old son disappeared into the stairwell without a trace. The police were called and after talking with residents, identified a suspect. However, the suspected neighbor has a solid alibi. You'd say that one tragedy was enough for the residential housing, but in another apartment, Yuan Wu's father dies suddenly after drinking. Yuan Wu and his father were short on money to begin with and now Yuan Wu doesn't know how he will continue on living without his father's pension. These weren't the only tragic events happening in this apartment complex - six months ago, Lin Chu Ping, a single female white-collar worker living alone, woke up in her home to find that she had been violated in her sleep. There is no trace of the perpetrator except for an ether handkerchief left on the windowsill. As the police continue their investigation these events become more entangled with each other, can they find Yang Mo before it's too late?
