Each group that had 20-30 children will undergo training for six months, in which at graduation they will enter a battle royal to be the one to survive. Lars, who managed to know this critical information by accident quickly told his friends and wanted the five of them to try and escape.
They planned out the details and planned to move the day before the graduation. But due to the carelessness of one of his friends they got caught. As Lars had the best attitude in class, he was spared from execution but would be punished.
His punishment? To be locked in a dark room in a one-meter square cage. Initially, he only needed to wait for one night which was mild compared to other punishments. That was until the screaming started. Another group of classes called "Poison" taught the children how and where to administer substances for maximum effect. And his four friends were used as guinea pigs for that class.
