Short on fuel, Kaz, Torra Doza, CB-23, Flix and Orka travel to Flix's homeworld of Drahgor III, a stormy world with deep mines containing fuel. Flix receives an icy reception from his estranged cousins, particularly Flanx. In returning for helping to repair a broken drill, Flanx agrees to supply the offworlders with fuel. Their mission goes awry when the lift malfunctions. While Torra and Orka climb back to the surface, the others are attacked by a large Karnex dragon, which captures Flanx. They rescue Flanx, but are attacked by more dragons. With the help of Torra and Orka, they manage to drive the dragons away and seal the entrance to their caves. Flix reconciles with Flanx, who gives the offworlders fuel. Realizing that they were encroaching on the dragons' habitat, Flanx ends deep-core drilling.
