Jack Finney

A small-town doctor learns that the population of his community is being replaced by emotionless alien duplicates.

Washington, D.C. psychologist Carol Bennell and her colleague Dr. Ben Driscoll are the only two people on Earth who are aware of an epidemic running rampant through the city. They discover an alien virus aboard a crashed space shuttle that transforms anyone who comes into contact with it into unfeeling drones while they sleep. Carol realizes her son holds the key to stopping the spread of the plague and she races to find him before it is too late.

The first remake of the paranoid infiltration classic moves the setting for the invasion, from a small town to the city of San Francisco and starts as Matthew Bennell notices that several of his friends are complaining that their close relatives are in some way different. When questioned later they themselves seem changed, as they deny everything or make lame excuses. As the invaders increase in number they become more open and Bennell, who has by now witnessed an attempted "replacement", realises that he and his friends must escape or suffer the same fate. But who can he trust to help him and who has already been snatched?
