"(narration) In the time of Superman's absence, Keystone City has become a utopia -- a protectorate relentlessly patrolled by a gale force once human. No one sees him... no one hears him. He runs a lonely race... but all who live here have felt his presence. He is everywhere at once... a guardian angel who rights even the most harmless of wrongs with lightning speed. He lives between the ticks of a second. He is The Flash."
