An insurance claims adjuster investigates mysterious events in a vault where incurably ill people are stored in cold sleep. The Company insured the whole world against everything and anything - but the premiums came high... The Company had brought peace and plenty to all on Earth - with comprehensive insurance against disease and disaster, war and want. Tom Wills gloried in his new rank of Claims Adjuster and relished his prospects of rising even higher. But then he met Rena, a enchanting young woman who turned out to be an Uninsurable - and involved in a conspiracy against the Company, to boot! To Wills, that is impossible, insane. Rena and her follow conspirators had to be deluded.. and it was clearly up to him to prove them wrong. The evidence he sought wasn't hard to find, so he began his investigation... and soon discovered that the real danger to the country, and the world, was the Company itself!"
