The lives of several people spanning from 1936 to 1993 are chronicled during their overnight stay at a New York City hotel room. Room 603 doesn't change over the years nor do employees age a day.
Each episode opened with the following narration:
"For a millennium the space for the hotel room existed – undefined. Mankind captured it and gave it shape and passed through. And sometimes when passing through, brushing up against the secret names of truth."
