It was a normal day at Louisville High. There was Lydia, the most popular girl at Louisville High surrounded by all her friends at their usual lunch table. There was Tyler, captain of the football team and most popular boy at school, laughing at a crude joke made by one of his friends. There was Giselle, the soon-to-be class valedictorian and nerdiest girl in school bent over her huge math textbook. Then there was Cole, the loner who sat at the last lunch table with his earbuds jammed into his ear, blasting his music. These people all have two things in common 1)Being at school before everyone else. 2) Being in serious danger. When someone brings a gun to school and locks the kids in, they have to fight for their lives and find a way out of the school. But, will they all escape alive.
