Down-on-his-luck college dropout Billy Danger shelters from a sleet storm in what he thinks is a corn silo, but which turns out to be a space yacht containing three upper-class hunters from a planet located halfway across the Milky Way.

Billy is nursed back to health by a giant tabby cat descended from pets that survived the starship crash.

A friendlier bunch of aliens arrive on Gar 28 and give Billy a ride to another planet, where he begins his quest to find and rescue Lady Raire.

After mastering the technical skills needed to crew a starship, he works his way across the galaxy, seeking the lady's homeworld.

His adventures include being captured on an espionage mission, which forces him to give up his right eye to ransom the lives of his fellow spies.
