Originally a collection of clips from the Neon Genesis Evangelion TV series, Death was created as a precursor to the re-worked ending of the series. Rebirth was intended as that reworked ending, but after production overruns Rebirth became only the first half of the first episode of The End of Evangelion, with some minor differences. Note that despite containing clips from the series, Death (True)^2 & Rebirth should be seen after the main TV series itself to be fully understood.

Having prevented the Third Impact and thus saving the planet, NERV unexpectedly finds itself under attack. Conscious of Gendou's betrayal, SEELE launches a massive attack on Tokyo-3 in order to conclude the Human Instrumentality Project at any cost. NERV must now fight its most fearsome opponent: mankind itself.

In a post-apocalyptic world, the last remaining human settlement in Japan is the heavily fortified city of Tokyo-3. 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. Although initially reluctant, Shinji is swayed by the idea of reconciling with his father, and agrees to aid in mankind's perilous endeavor against its alien threat, as the pilot of Evangelion Unit-01. Thrust into the midst of a dangerous battlefield, Shinji must find the necessary courage and resolve to face against the Angels' incursions before it is too late.

When the threat of the Angel menace escalates, mankind's defense force is pushed to its limits, with Nerv at the forefront of the struggle. Shinji Ikari and his partner Rei Ayanami are assisted by two new pilots: the fiery Asuka Langley Shikinami and the mysterious Mari Illustrious Makinami. With the aid of their mechanized Evangelion units, equipped with weapons perfect for engaging their monstrous opponents, the four young souls fight desperately to protect their loved ones and prevent an impending apocalypse. But when startling secrets are brought to light, will the heroes' greatest challenge prove to be the monsters...or humanity itself?

Fourteen years after third impact, Shinji Ikari awakens to a world he does not remember. He hasn't aged. Much of Earth is laid in ruins, Nerv has been dismantled, and people who he once protected have turned against him. Befriending the enigmatic Kaworu Nagisa, Shinji continues the fight against the angels and realizes the fighting is far from over, even when it could be against his former allies. The characters' struggles continue amid the battles against the angels and each other, spiraling down to what could inevitably be the end of the world.

In the aftermath of the Fourth Impact, stranded without their Evangelions, Shinji, Asuka, and Rei search for refuge in the desolate red remains of Tokyo-3. But the danger to the world is far from over. A new impact is looming on the horizon—one that will prove to be the true end of Evangelion.
