Fourteen-year-old Shinji Ikari is brought to the headquarters of Nerv, an underground organization lead by his estranged father, Gendou. He requests that Shinji become a pilot of an "Evangelion," a colossal android built to fight against monstrous and destructive alien creatures known as "Angels" that wreak havoc on the planet and threaten the survival of the remaining human race.
