What happens
Buzz Corey and Happy investigate contaminated food shipped from a chemical farm on Venus. Their agent Tonga has gone undercover there as a chemist and has discovered that a racket is bribing workers to poison the hydroponic tanks of farms that refuse to pay protection money. Corey and Happy head for Venus, where they find the farm of Milton Eagle and his associate Richard Baxter, and they soon face hostile forces involving sun mirrors and a captured agent. This is the opening portion of the Space Patrol episode The Space Shark, which was broadcast on December 6, 1952.

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.
