They are the rebellious age of teenagers. Some of them squander their parents' money and become the first brother in school; they may have stolen their parents' money, they may have stayed up all night in bars, or they may have called themselves gangs and fought with others. Just when everything seemed hopeless, the parents of these children learned that there was an academy located in a small county town - and all the problems of these children, whether they were naughty or idle, would be solved there. Parents who are helpless about their children regard this as their only hope. They use all means and pay all costs to send their children there. After waiting for many years, their children will become obedient and obedient. These children resisted to no avail, and were eventually sent to this four-high wall that was isolated from the outside world. What awaits them is endless darkness, torture, tears or blood. Life has become so worthless, and all self-awareness will be crushed into powder. "Only by escaping can you be a human being, not an animal." Can you escape? Run away.
