The Body Snatchers

Mill Valley, Marin County, California.

Dr Miles Bennell has lived there all his life. But one day Miles sees a patient who claims her Uncle isn't himself. He's a different person, despite being identical in every way except one: he is only pretending to have emotions.

Miles dismisses this as delusions and refers her to a psychiatrist.

Then he finds the pods. Giant seed pods, filled with a strange, grey substance. A strange grey substance that can slowly, slowly, become a perfect replica of a person.

But what has happened to the people being replicated?
