Five Strangers, One Fatal Detention

It begins like a twisted version of "The Breakfast Club": five students walk into detention at Bayview High, each fitting a distinct stereotype. Bronwyn is the Yale-bound perfectionist who never breaks rules. Cooper is the baseball star with major league scouts watching his every move. Addy is the picture-perfect girlfriend whose identity revolves around her popular boyfriend Jake. Nate is the school's notorious drug dealer, already on probation. And Simon-well, Simon runs the school's feared gossip app that exposes students' darkest secrets. All five insist they're innocent, claiming someone planted phones in their backpacks to get them into detention. But what starts as an ordinary punishment takes a deadly turn when Simon drinks from the water cup and collapses from a severe allergic reaction. Despite frantic efforts to find his EpiPen and perform CPR, Simon dies on the classroom floor. The investigation quickly reveals this was no accident. The EpiPens were deliberately removed from the nurse's office, and peanut oil-fatal to Simon's documented allergy-was found in his cup. Even more damning, police discover Simon had scheduled a gossip post for the next day exposing devastating secrets about all four detention survivors. Suddenly, everyone has a motive, and the "Bayview Four" become the prime suspects in what now looks like murder.
