Sam and Mary take a short leave, get married and have a happy honeymoon that is interrupted by a slug that seems to have been targeting Sam for repossession. They return to work and discover that people are now required to be practically naked as the slugs learned to attach themselves to other body parts. Together with the Old Man, they go to Pass Christian, Mississippi, to inspect a flying saucer that had made a bad landing. Inside the alien ship, Mary is overwhelmed by repressed memories from the time she was a child on Venus and had been possessed by a slug. The slug had died from "nine-day fever", a deadly disease native to Venus.
