A Wind Named Amnesia / Invader Summer

The Apocalypse didn't end with a BANG, but with a whimper. Silently, the 'amnesia wind' swept away all of mankind's knowledge. Thousands of years of human civilization vanished overnight as people forgot how to use the tools of modern civilization; who they were, how to speak - everything! Technology decayed as mankind was reduced to an extremely primitive level. Two years after the devastation, a young man explores a nation reduced to barbarism: America. Miraculously re-educated after the cataclysm, he is accompanied by a young woman - somehow spared the obliterating effects of the amnesia wind. Pursued by a relentless killing machine, they search for those responsible for stealing their memories.
