Detention {based on Detention 2012 movie}

Riley Jones is a social outcast with a relatively popular friend, which confuses everyone. No one understands why Clapton Davis, the high school 'it guy' is friends with a suicidal freak, not even Riley understands. The last year of school is nearly finished and prom night is in a few days. But will there be a prom when a mysterious murderer starts to kill the student body? Can a bunch of students work together to find the mysterious killer that hunts on the seniors and stay alive? Will Riley ever have the courage to speak of her love for Clapton before it's too late?
