At the edge of the Solar System, CAPTAIN FUTURE and the Futuremen discover a plot of interstellar proportions as they confront THE GUNS OF PLUTO. “Cold Hell” was what they called the Sputnik Planitia Penal Colony on Pluto: the toughest, deadliest penitentiary in all of space, a lock-up so remote and forbidding that it was built within an immense iceberg and is guarded by a race of cannibals.
