The whole story focuses around Motoko Kusanagi, a cyborg assassin that has the abilty to turn invisible by stripping off her clothing, which is awesome! As for the plot, she is being stalked by a ghost-type creature called the puppet master, who is erasing the memories of his victims.
There is a lot more to the plot, but telling you about it might get me in trouble with the spoiler police. Anywho, just buy the video like I did, watch it, then watch it again to make sure you didn't miss anything, then watch it again for no good reason...*drool* uh, nevermind......
(Olikrom adds: I feel the writer was being too harsh on the rating. He gave it a 7/10. I gave it a 8.5/10, because It really has a good story to it, but I felt confused at times.)
