This story is pure fiction, thriller and horror. It turns out that during a school retreat, the students of a class find themselves alone and locked in the Mafia Game. There are the Citizens who must find the Mafias, and they are helped by the Police and Doctor, while the Mafias must kill all the citizens. Every day, the Citizens must vote for a person they believe to be one of the Mafias, and they must then hide during the night because they are immobilized in a sleep while the Mafias hunt to kill them. It's a cruel and bloody game of cat and mouse that gives rise to desperate and even psychopathic characters.

The series really took the storytelling from a fairly human and brutal angle. We end up with teenagers who kill each other and betray each other between friends, who do unspeakable acts to each other, and the worst is that we can sense desperation and that they hate the fact that they have to do this to survive.

The key word is not to stand out to draw suspicion, and until the last episode there were revelations about characters that we didn't suspect.

The only downside is the ending, although I was expecting a sort of simulation, and that it spoils the story a bit as unrealistic, it teases a second season that I hope will see the light of day. Otherwise, even with this kind of ending, the series is very much enjoyable for its thrilling and suspenseful moments.
