Joshua Regan, an ambitious investigative journalist is assigned to write an article on the apparent increase of UFO sightings and supposed 'alien abductions'. His lack of enthusiasm for the story is evident until he stumbles across Jimmy Stock, a London minicab driver who is a victim of a savage attack which has left him deeply traumatised. Roger Coffey is an astronaut with NASA and a last minute replacement for an old friend who has astonishingly taken his own life. Coffey soon becomes aware that despite his presence on the 'Prometheus' mission, he is clearly an outsider. The suspicion that his crew are carrying out an irregular satellite deployment soon becomes validated as he realises that his own life is in immediate danger. Regan and Coffey's lives become inexorably intertwined in the wake of a profound global event which will usher in a terrifying new age of world order.
