It was basically just a bunch of highschool kids getting offed one after another in Saw style traps/games. Complete with a twist ending. It takes place in a boarded up school Danganronpa style and goes decently hard on the gore.

One of the traps involved everybody putting their hands into increasingly horrible things like live bugs, a heater and the like, while the middle had nothing in it at all. The middle one was the trap though and if you picked it you got your arms cut off.

Another had a crushing style death that I dont remember too much of, except that it involved a "Couple" who quickly tried to fuck each other over to not die.

The premise is a big set up ala "I know what you did last Summer" where all of the characters present were part of a bus crash that left it teetering on a cliff edge, and the twist is that one of the group was killed before the story started, and replaced by the mother of the family on the bus that none of the kids tried to save.
