14 students in an attic. Only 9 come out alive. What happened?
Ayla Zayn is a 16-year-old student in her last year of Valley Green Girls' School. It's December and the snow is falling fast as time goes by. And then, a body is found. From there, it snowballs into a huge mess.
DI Youngchae Shin is investigating the murders of 5 teen girls after them and their 9 friends got stuck in an attic. The girls have been murdered brutally, but by whom?
Mature: Literal murder-
Three girls stay over in a cabin. Only two come out alive, but with no memory of what happened the night before. A murder occurred, but no evidence to say who did it.
No suspects, no witnesses.
What happens when the people you trust the most, are not who you think they are? And is the killer finished? Or are the murders just getting started?
