In 1999, Professor Allan Neyman and Connor MacLeod develop a shield to protect Earth from the radiation caused by the damage in the ozone layer. Twenty-five years later, Earth is dying due to the effects of the shield and the terrorist group commanded by Louise Marcus is trying to destroy the shield.
