Tough Guy Trask murdered a Space Patrol, so he’s slapped with a life-sentence in a labor camp on one of Jupiter’s moons. Another prisoner, the Martian Gror, tells Trask of his plans to escape on the next spaceship, and shows him a “Martian gas gun”. Later, Trask is working on a bridge over a valley and intentionally bumps Gror off it, killing him. Trask rushes to Gror’s lifeless body and secretly retrieves the gun. Trask uses the gun to escape, boards the spaceship Gror mentioned, but discovers the ship itself is a prison, and a death trap.
