Well.. One day there was a strange wind and it made everyone forget everything but theire basic instincts like to eat.. sleep.. act violently and kill.. etc.. anyway there was supposivly somebody behind this from a greater power, they wanted to see what human beings would do without all their technology and what made man tick basically. Anyway one person saw a boy in a wheelchair(Johnny?) about to get attacked by this big ugly monster with wires sticking out of him and he knew that he had to help the kid.. so he picked up a big rock and threw it at his head! Then it got pissed off but the kid pulled out a pistol and shot it.. anyway the kid helped him get some smarts with a machine and the kid told him to go out into the world and explore when he died.. and he did die after a while and so he started his journey, he met a woman and explored several areas, but there are a few 'guardians' which are machines that are still working even though nobody is piloting them and they kill people, anyway they are hunted down by them but he always kills or gets away from them.. anyway it turns out the chick is sort of behind the amnesia and she was sent down to see how the humans would act.. and toward the end they supposivly will get their memories back and thats that!
