The Searcher rescues a gold-skinned boy from an escape capsule in an asteroid field. When the ship collides with one of the asteroids, the boy displays his powers of molecular alteration by rescuing Admiral Asimov from beneath a fallen girder. The boy assures the crew of the Searcher that, with the help of his companion, who is on a nearby planet, he can dislodge the ship from the asteroid. But when Buck and Hawk go to the planet to get the companion, they find that he is being held captive by a man who wants to use the boy's powers for his own greedy purposes.

An ancient videotape is discovered that proves that Buck was involved in the nuclear holocaust that nearly destroyed the Earth hundreds of years before. Commissioner Bergstrom convenes a war crimes trial aboard the Searcher and, if Buck is found guilty, faces a death sentence. In a desperate attempt to clear himself, Buck agrees to another mind probe, but his memories seem to confirm the charges.

Buck and Hawk are sent to pick up the survivors of a planetary disaster and transport them to a new home. Before departing, Buck rescues a young woman from a group of Dorian thugs. Later, while enroute to the planet, the Searcher is attacked by a Dorian craft, which demands that the woman be returned for the murder of a warlord's son. As the Dorians persist and subject the Searcher to a severe pounding, the refugees begin to rebel, insisting that the woman be turned over. Eventually, Buck discovers that truth about the woman and the startling reason why the Dorians always wear what at first appear to be merely ceremonial face masks.
