It’s being described as a comedy-horror in the vein of This is the End, and, it has elements of Scream.
Here’s the plot, per Deadline:
At Senior Night, the school rents out an amusement park for the entire senior class where everyone rides the rides and plays the games as much as they want with no lines and no rules. The only drawback: students start dying on the rides in elaborate ways. All the exits are sealed, and there is a killer on the loose turning all the rides into ways of punishing the bullies and the so called bad people at school. Kids from all different cliques have to band together to figure out who the killer is and how to stop them.
Fox is shepherding the Cohen and O’Brien film. We’ll let you know when it begins production…
