Millionaire Paul Radin invites three people to the bomb shelter that he has built. He greets them politely but without genuine warmth as he holds a personal grudge against them all. One is a high school teacher (Mrs. Langsford), who failed him as he was caught cheating on a test and attempted to frame another student to avoid being caught; second is Colonel Hawthorne, who had him court-martialled as he endangered lives due to disobeying orders; and the third is Rev. Hughes, who made a public scandal out of a woman who committed suicide over him.
