Having rescued Captain Kidd from Dragos' booby trap, the pirate agrees to join the fight against the alien tyrant. When the Starfire's navigation system is disabled, the Captain uses his sextant to calculate their location and course and the spaceship arrives at Space Academy just in time to thwart Dragos' latest attack by his ship's guidance system, sending his vessel adrift in deep space.
