"That's Oliver Crangle, a dealer in petulance and poison. He's rather arbitrarily chosen four o'clock as his personal Götterdämmerung, and we are about to watch the metamorphosis of a twisted fanatic, poisoned by the gangrene of prejudice, to the status of an avenging angel, upright and omniscient, dedicated and fearsome. Whatever your clocks say, it's four o'clock - and wherever you are it happens to be the Twilight Zone."
Oliver Crangle is a bitter, prejudiced man. Through unknown means he intends to shrink every evil person in the world at four o'clock. When four o'clock comes around, it is he who shrinks."At four o'clock, an evil man made his bed and lay in it, a pot called a kettle black, a stone-thrower broke the windows of his glass house. You look for this one under 'F' for fanatic and 'J' for justice - in the Twilight Zone."
