In a dystopian future where the crime rate has skyrocketed, Manhattan Island has been transformed into the ultimate maximum-security prison. With a colossal containment wall surrounding the island and all bridges and waterways mined, prisoners inside are left to form their own anarchic society. No guards are present within the walls; once you're in, there's no legal way out. The rules change, however, when the president of the United States’ plane is hijacked and crashes into the desolate urban wasteland.

A convicted bank robber and former war hero with nothing to lose is offered a deal he can't refuse – pardon for his crimes in exchange for rescuing the president, who is trapped within the city and is carrying a tape containing vital information for an upcoming summit. Time is against him as he has less than 24 hours to complete the mission. With a tracer device and explosive charges implanted in his neck to ensure compliance, he must navigate through the chaotic streets of New York, facing treacherous inmates and remnants of society in ruins.
