"Tricked by the Imperial Alliance, X-Bomber is caught in the Black Hole of Sargasso, its power reserves fading fast; Commander Makara sends Imperial fighters to force X-Bomber to expend more power. But Dr. Benn summons all X-Bomber's resources for a gigantic laser blast on the alien battle cruiser. Makara's attack is repelled but the X-Bomber is trapped in the gravitational grip of Sargasso and virtually without power. Lamia calls to the mysterious Skull for help, and the strange ship proves its loyalty by pulling X-Bomber to the safety of free space. But before X-Bomer can discover the secret of the Skull, the space galleon disappears."
