Marvin Martin, the show's host, is angry. Night after night he strips his guests of their pitiful pretensions, their commonplace hypocrisies - but how long has it been since he uncovered a genuine revelation? Hurwitz, who selects Martin's victims, is scared. He made a bad mistake when he chose Doris Jensen; she turned out to be from a competitive network and ruined a taping. Hurwitz's job is in danger. Walter Monaghan, historically, the 29th man to have walked on the moon, is desperate. He wants to tell the Revelations audience the truth about America's "space program" - that it never got off the ground. If he's just another nut, why is it so important that he be silenced?
