Many years ago, a bizarre alien life form known as the Black Mass destroyed a solar system in what was then the Thallonian Empire. Now the Black Mass has returned and the fearsome Redeemers of the planet of Tulan IV must turn to an unlikely ally--Captain Calhoun and the Starship "Excalibur"--or face total destruction.
