Captain John Strong leads a group of space-pioneers to Ganymede. Along with him are Peter and his sister Peggy, who is in love with Captain Strong. Settling on Ganymede gets complicated when a man named Maddock discovers diamonds, gold, and uranium. Maddock and his cohorts desire to return to Earth with their new riches. Strong argues that the Ganymede settlement is the true treasure, leading to fisticuffs between Maddock and Strong. Maddock is the decided loser in the argument. Maddock and his lackeys blow up the food stores in an attempt to get the people to leave Ganymede. Strong can’t prove Maddock’s involvement, but lets the man know his suspicions. Strong sets up a hydroponic garden to support the food needs of the colony, using their rocket’s power to grow the food. Maddock pulls a gun on Strong, insisting on taking the rocket and returning to Earth. Instead of fighting the maneuver, Strong agrees to go along with Maddock and his men as a pilot and “astronavigator”. Peggy bemoans falling for Strong, whom Peter calls a “cowardly space-crawler” for the Captain’s treachery. Once in space, Strong takes over the ship and turns on the radio. The broadcast from Earth announces the discovery of an inexhaustible supply of uranium on the Moon, making the discovery on Ganymede worthless. Strong tells Maddock and his men that the announcement saves them from being criminals. They change course to return to Ganymede and Peggy, the woman he loves.
