What happens
Superman and Clark Kent visit Bruce Wayne's house to seek help from Batman, after two pieces of deadly Kryptonite fell into the hands of unknown enemies. Wayne is suspicious at first and asks Kent for proof of his identity. Once Superman convinces him, Batman and his partner Robin agree to help track down the Scarlet Widow and the secret organization that uses a crescent and star symbol. The heroes plan their next steps together. This part of the adventure is a serial episode of The Adventures of Superman, first broadcast on December 7, 1945. The lead actors are not named in the transcript.
Bruce Wayne's library and house, then the shabby waterfront district of the city at early evening, with fog rolling in from the harbor.
Characters: Superman, Clark Kent, Batman, Bruce Wayne, Robin, Dick Grayson, Squeely Evers, Scarlet Widow
Listen for: Clark Kent's proof that he is Superman, and the plan to track the crescent-and-star symbol to the Scarlet Widow and the Kryptonite.
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.
