In the near future where Android (A.I) becomes common among humans, a virus outbreak suddenly occurred, turning over 70% humanity into zombie-like Creatures. The A.I soon break away from their infected owners since theyre not programmed to recognize Creatures as humans, but one of them, the housekeeper Hasty, acted otherwise when her infected young master, Nevilles final words struck something in her. Sticking with him after all other humans have been infected in the area theyre living in, Hasty vows to do whatever it takes to cure master Neville, even if she has to fight against the whole world whos now looking to exterminate all Creatures to cut off the infection source completely.
