K Star men sneak onto the earth and mind-control many elites of human society, making humans kill each other and the earth fall into total chaos, as that K Star men can launch a full-scale attack on the earth... To crush K Star men's conspiracy, the earthmen set up a special organization and begin to hunt down the human elites working for K Star men. However, when many human elites are eliminated, the killers come to realize that they have killed the wrong men -- those who are really working for K Star men are not the killed, but are the killers themselves...
