Or use the Warsaw "ghetto" model?
In the future, crime is out of control and New York City's Manhattan is a maximum security prison. Grabbing a bargaining chip right out of the air, convicts bring down the President's plane in bad old Gotham. Gruff Snake Plissken, a one-eyed lone warrior new to prison life, is coerced into bringing the President, and his cargo, out of this land of undesirables. The world's greatest leader is a hostage in the most dangerous place on Earth.The author did ok except for thinking the US president would be “the world’s greatest .eager.”
Think “Escape from New York” sort of thing
