In this comic suspense story, sixth-grader Allison Parker (Katie Stuart) likes to imagine herself something of a detective, keeping tabs on what goes on in her neighborhood and communicating with her best friend Jane Walker (Emily Lipoma) via walkie talkie. (In the manner of good spies everywhere, Allison used the code name "Frog" when talking via radio and insists Jane call herself "Wombat.") However, when the girl's new principal, Larry Struble (Ronny Cox), moves in next door, Allison begins to wonder if she might have a real mystery to investigate when Larry's niece Nancy (Jessica Cashman) disappears a few days after he's moved in. Convinced foul play is afoot, Allison begins snooping, with Jane her reluctant helper, though Jane is hardly as convinced as her friend when she decides that a missing refrigerator, a stray wedding ring, and some photos of a mystery woman add up to murder. Lindsay Wagner also appears as Allison's mother, in whom Larry seems to have taken an interest.
