Poised to enter a new and unexplored section of the galaxy, the Space Star Silver Streak is intercepted by a massive alien starship. A mysterious being known as Starjudge demands that Captain Richard Cameron surrender himself.

The Hyron commander Mordrax, still in hot pursuit of his old enemy Cameron, is similarly arrested in space, and presently the two foes are face-to-face with a giant, centipede-like alien who places them on trial--with their identities at stake!

As Cameron and Mordrax battle for their individuality, Science Officer Philippe Stargazer finds himself awkwardly attracted to his daughter Servanne--this as she prepares to become engaged to the handsome young hero Trevor Lansdowne.

Personalities clash and deep secrets are revealed in the most stunning and intimate Voyage Into the Unknown adventure of them all!
