Beyond the Spectrum is set in the year 2956, the 30th century. It concerns an invasion of Earth by the inhabitants of the invisible planet Nihil. Nihil is invisible due to an odd defect in the fabric of space between it and most of the other planets.

The first evidence of hostility happens as a young couple, Addis and Bia, are enjoying themselves; Addis gets knocked out by a stun ray gun and gets taken away into an invisible craft. Earth attempts to stop the invasion using a team of psychics, utilizing their psychic abilities to find the enemy, gather more intelligence on them and help the military capture an alien vessel and its crew.

It is discovered that the people of Nihil exist like an insect colony, mostly sterile, with drones that carry out the majority of work, and an intellectual class that runs the society and directs the war against Earth... under the leadership of an incredible intellect that is the emperor. Alida, a junior psychic, is abducted and taken to Nihil where she conducts an unorthodox method to try to undermine the enemy.
