Moonstruck

After World War THREE, in which a the ultimate nuclear bomb was used, all countries on earth have been completely demolished. All except the bomb's perpetrator, a country once called America. Now with the entire world's population living in one country, government leaders are faced with a dire over population problem. In order to keep over crowding at bay, a chip is invented, one which is injected into each newborn child and activates at the age of 16. It enables the body to fight off any disease which confronts it, but with this comes a price: it also causes drastic aging and an early death of old age from late 20's to early 30's.
