Five Bayview High School students are sent to school detention after school, and only four make it out alive. Simon, a scoundrel who created an app with actionable content about students' secrets, dies. And as investigators determine, his death was no accident. He died on Monday, and on Tuesday he was planning to reveal juicy secrets about the other four students who were in his class, which is why all four are suspects in the murder. Or are they the perfect scapegoats because that's what the killer, who is still at large, planned? Everyone has secrets, right? The question is, how far would they go to cover them up?
