No one believes that the Vorvon, who sneaks up on his victims and drains their living soul, is responsible for a series of deaths on Space Station Theta except Wilma -- his next intended victim.

Princess Ardala returns with another plan to snare the man from the 20th Century. This time, she captures Buck by luring him aboard a phoney 20th Century spaceship like his Ranger III. Once aboard the flagship Draconia, Kane creates four duplicate androids of Buck in an attempt to have them pilot the Draconian Hatchet fighters in an attack against Earth.

Buck is invited to be the special guest of the 2492 Olympics. Shortly after arriving on the planet where they are being held, he is drawn into a game of political intrigue as an athlete from the planet Lozira attempts to defect to Earth.

Buck journeys through a space warp into another universe, where he discovers that the peaceful planet Pendar is being threatened by the sinister war witch Zarina. The Pendarans enlist the aid of Buck and Princess Ardala, who had followed Buck through the space warp, and an unsteady alliance between the humans and Draconians is formed as Buck leads a combined fleet against Zarina's battlecruiser.
