What happens
Clark Kent, who is secretly Superman, has recently survived a battle with the atom man, Henry Miller. He first visits scientist Dr. John Millicent, who gives him a detector belt meant to sense kryptonite and warn of the atom man's approach. Back at the Daily Planet, Kent is visited by a wealthy, scheming man named Sidney. Sidney claims to have studied Superman and says he plans to publish a report revealing Superman's true identity. He invites Kent to his country estate to examine his files. Kent agrees to go that evening, and Sidney's visit leaves Kent uneasy about what Sidney knows.

Written from the episode itself; it never gives away the ending. Every recording is remastered for the stream: cleaned of rumble, hiss and mains hum (and the old TV whine where we found it), then levelled in two passes to steady broadcast loudness, so one show is never quieter than the next.
