1997. New York City is now a maximum security prison. Breaking out is impossible. Breaking in is insane.
In 1997, the island of Manhattan has been walled off and turned into a giant maximum security prison within which the country's worst criminals are left to form their own anarchic society. However, when the President of the United States crash lands on the island, the authorities turn to a former soldier and current convict, Snake Plissken, to rescue him.
