Meet two of L.A.’s finest: Sykes – the veteran and Francisco – the alien.
The time – a future closer than we know. Where groups of extraterrestrial aliens have become familiar members of our society.
The place – Los Angeles. Still a town of fast times and hard crime, touching every life form inside the city limits.
The cops – Sykes, earthman, and Francisco, alien. Facing a menace meaner than the meanest streets on their beat. Fighting an enemy as terrifying as the darkest forces in a vast, unfathomable universe. Battling back with the best – and the deadliest – of both their worlds.

Based on the screenplay by Rockne S. O'Bannon; novelisation of the Graham Baker movie.
