With the rise of the Iron Age in feudal Japan, man and nature grow increasingly at odds. As mankind infringes more and more into the kingdom of the beasts, many of the elder animal gods begin to succumb to their rage, cursing themselves as they lash out at rural and urban settlements alike. When a young Ashitaka, hero of his village, is imparted with one of these curses after slaying a crazed god, he forces himself into exile to prevent further harm to his village. As he ventures out into the world, however, he discovers just how dire the straights have become - with man and beast ready to break into all out war, his curse becomes the least of his problems. As both sides teeter dangerously on the side of outright slaughter of one another, Ashitaka sets his own problems aside and, using his charisma and honor, seeks to quell the hatred before it gets beyond repair - but will he be in time or is he simply delaying the inevitable?
