The majority of Earth's fighter squadron becomes incapacitated after using poisoned food discs. Buck, Wilma, and Duke Denton fly to the distant planet of the food's origin, Vistula. They seek to track down a slave trader named Kaleel who is collaborating with the planet's governor. While on the planet Vistula, they find that Kaleel has been building a fleet of attack ships in secret, and plans to use them against Earth's weakened defense forces. With Earth's defense force now heavily outnumbered 10-to-1, Buck decides that he must destroy the attack fleet and rescue Wilma, who has become trapped in Kaleel's mountain fortress.
