In 2015, fifteen years after a global cataclysm known as the Second Impact, teenager Shinji Ikari is summoned to the futuristic city of Tokyo-3 by his estranged father Gendo Ikari, the director of the special paramilitary force NERV. Shinji witnesses the United Nations forces battling an Angel: one of a race of giant monstrous beings whose awakening was foretold by the Dead Sea Scrolls. Because of the Angels' near-impenetrable force-fields, NERV's giant Evangelion bio-machines, synchronized to the nervous systems of their pilots and possessing their own force-fields, are the only weapons capable of keeping the Angels from annihilating humanity. NERV officer Misato Katsuragi escorts Shinji into the NERV complex beneath the city, where his father pressures him into piloting the Evangelion Unit-01 against the Angel. Without training, Shinji is quickly overwhelmed in the battle, causing the Evangelion to go berserk and savagely kill the Angel on its own.
