Photographer Steve Blake witnesses a fatal car crash but is surprised to find the victim alive and well the next day. Investigating further, he finds several similar cases, and uncovers the village of Sweethorpe, which fell into the sea five years earlier, with no loss of life.

Blake, investigating the highly successful careers of the Sweethorpe survivors, gets a job at a software plant owned by another Sweethope survivor but is soon uncovered. Melissa Gates falls foul of the local M.P.

Melissa survives the car crash, but Blake worries that she might have been renewed like the Sweethorpe victims. They decide to reveal their theory of alien invasion on national television.

Blake is denounced as a terrorist responsible for the explosion at Sizewell power station, and goes on the run with Melissa.
