Alan Moore is sent to the moon piloting an atomic powered space ship designed by Professor Manheim. This trip marks mankind's first foray into space travel. Amazed at the high rate of speed, Alan is surprised to come across another space ship. The craft sends a beam at Alan's ship, capturing in a "magnetic pull". Once aboard the other craft, Moore is addressed by the Martian space pirate Jana. Jana flees the Mars-Venus Patrol. The pirate has made captives of Professor Fenrir and the professor's daughter, Desua. Jana's craft has run out of fuel, and he intends to use Alan's ship to refuel the atomic engines. Alan resists, but is overcome by superior numbers.
