Sam Wentworth is not sure about his new friends. On his first day of a new school, Sam is surprised to fall in with the popular crowd--it's all because he plays the same online video game as some of the football players. But the way they bully other gamers bothers him. Then, they get their hands on a pirated copy of the "The 13th Floor", a game banned for violence and gore. Sam and his new friends find the game so hypnotic that they can't stop playing, even after bad things start happening to them.
