Second miniseries, following on from ARM, adapting the Larry Niven detective stories starring telekinetic ARM (Amalgamation of Regional Militia) agent Gil "the Arm" Hamilton. The Defenseless Dead who provide the story's title are "corpsicles", people who had themselves cryogenically frozen in the hopes of being eventually revived in the future, either because they suffered from medical conditions which could not yet be cured or simply in the desire of being woken in what they hoped would be a better era than their own; however, the corpsicles were now gradually being declared legally dead by the UN, so that their organs could be harvested for transplant.

When Hal Jordan is visited by the Guardian Ganthet, he learns the Guardians most shocking secret and faces off against a renegade Guardian whose machinations threaten the existence of the universe.
