Bill is a farmboy on a small backward agricultural planet who is drugged, hypnotised, then shanghaied into the Space Troopers and sent to recruit training under a fanged instructor named Deathwish Drang. After surviving boot camp, he is transferred to active duty as a fuse tender on the flagship of the space fleet in battle with the Chingers, a small reptilian race who are, in Trooper propaganda, portrayed as being 7 feet tall. Before the battle one of Bill's fellow troopers, known as Eager Beager, is revealed to be an android operated from within by a Chinger, who is in fact only 7 inches tall. Injured and with the fleet almost destroyed, Bill accidentally fires off a shot from his ship's main gun. The shot is witnessed by an officer and Bill is proclaimed a hero.
