All will participate. One is guilty. None are safe.
"When It's Night" is a locked-room progressive whodunit centered around 15 high school honors students who were selected to be invited for a mostly informal get-together hosted by the school's founder, ██████████, in celebration for being the school's most successful alumni.
All of them decide to come, but once they explore the area, they find multiple incriminating sights, including dead bodies, and then soon realize they have been trapped inside.
When night comes, someone has been killed, and the students find out that one of them is a murderer.
It is now up to the rest of the high school students to solve the mystery and find the murderer...
...if they can.
The beginning of the story takes place on Thursday, May 23, 2030.
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?
