In important points of the geography of the United States a strong invasion is taking control of communications, the government, industry ... and peoples' bodies. The country isn't capable of stopping the invaders, who grow rapidly and control the minds of any fool who crosses their path. That is when Sam Cavanaugh comes into action, effective intelligence officer of the unknown section of the United States Secret Service. Cavanaugh is the only man who can stop the invasion, but to do so ... he will have to be invaded himself!
