S.S. Escape

I had never wanted to be dumb in my whole life more than right now. I always felt an advantage over kids at my school because they always came to me for help, they always got lower than a B on tests, they always got "needs improvement" on grades.

A dream turns into a nightmare when a student aboard a high school cruise ship where only the smartest students get to attend has been murdered. Passengers are told to lock themselves in their cabins and wait for directions. The captain speaks from the ship's video news broadcast system "The first contestant has fallen, only ninety nine remaining." With that, the door clicked and swung open.
