Science Fiction Story: It's another tale of the three young men who serve in the Solar Guard as Space Cadets. The Solar Guard is establishing its first colony on a star far away in space, and of course, our heroes are in on the mission. But somehow a villain named Paul Vidac has wormed his way into the Cadets' assignment -- replacing Capt. Strong as Lt. Governor. The man means nothing but evil, and if the cadets don't catch him at it, it'll be the end of them for certain.
