Doomsday / Escape From New York

Doomsday:
Mankind has an expiration date

Great Britain, 2007. A deadly plague, known as the "Reaper Virus," has broken out, killing hundreds of thousands in its wake. In desperation, the British Government evacuates as many survivors as it can out of the infected area, and then builds a wall, preventing the remainder from escaping. Thirty years later, with the wall still up and the victims all but forgotten, the virus breaks out again. The Government decides to send a crack team of operatives, led by Major Eden Sinclair, into the hot zone to investigate the possibility of a cure

Escape From New York:
1997. New York city is now a maximum security prison. Breaking out is impossible. Breaking in is insane.

The year is 1997. New York is a maximum security prison where hardcore criminals are put for life. All the bridges leading into the city are mined and and a large police force army is prepared to kill any attempted escapees. En route to an important conference, the President, on board Air Force One, is forced to eject in a pod when a terrorist takes over the controls and crashes the plane. Snake Plissken is offered his freedom if he goes in, frees the President and finds a tape with important information for the conference or he will die. Snake must set out into the decaying city, filled with immoral criminals, and he must succeed for his own life.
