This Synopsis was written by me.
In the year 2000, a mysterious "meteorite strike" on Antartica wipes out half the human population. In 2015, the survivors of this so-called "Second Impact" cower in subterranean cities, while a war is being waged for what remains of planet Earth. On one side are the strange and powerful beings called Angels; and the other, the secret agency of NERV, with mankind's last hope: the giant cybernetic robots called Evangelions. But only children born after the Second Impact can pilot them. The estranged commander of NERV, Gendo Ikari, summons his son Shinji(whom he had abandoned years ago) to be the pilot of Evangelion Unit 01. Shinji is taken to live with the sisterly Misato, but he suffers many hectic incidents while piloting the Eva and fighting Angels. Also, he still detests his father for abandoning him, and he's often reluctant to fulfill his role as an Eva pilot.
Soon, Shinji's joined by two other Eva pilots; stoic Rei Ayanami and fiery Asuka Langely, and it becomes apparant that only Evangelions possess enough power to defeat the attacking Angels. But there's more going on behind the scenes than just a war with the Angels. The sinister group called SEELE, which sponsers NERV, wants the Evangelions for a more darker purpose than just battling Angels. But the true threat to the human race may not be the Angels, but the tragedies of the people themsleves, and the incomplete void that consumes all our hearts, unless we learn to take care of ourselves.
